The Ardsley, 1931. Completed in 1931 the building remained "The Ardsley," though it was a very different structure. Designed by famed Art Deco architect Emery Roth, the now 22- story building was a Mayan inspired Deco masterpiece. Because of the changes in zoning in 1916, taller buildings were required to include setbacks for increased light and air. Roth took this requirement and ran with, creating ziggurat-like setbacks decorated with Mayan style motifs and executed in black brick on a beige facade. The apartments within were smaller and less extravagant than the ones in the previous building (large rooms but no servants quarters). The exception to this was the triplex on the 21st, 22nd, and 23rd floors. This 11-room suite included 15-foot ceilings and a wood-burning fireplace in every room. Its occupants also had access to a wrap-around terrace on the 21st floor and two terraces on the 22nd floor.

Eldorado Apartments ARCHITECT: Margon & Holder; Emery Roth DATE: 1929-31 STYLE: Art Deco The Eldorado, extending along the entire blockfront of Central Park West between 90th and 9lst Streets, is the northernmost of the four twin-towered apartment houses that give Central Park West its distinctive skyline silhouette. The Eldorado was designed in 1929 by the architectural firm of Margon & Holder with the renowned early 20th-century New York City architect Emery Roth as a consultant. These architects created one of the finest and most dramatically massed Art Deco style residential buildings in New York City.

The Beresford, ca. 1913. The Beresford was an apartment hotel built from 1889-1892 on the northwest corner of 81st Street and and Central Park West. It was superceded by the Beresford Apartments, built 1928-29.

Tanner's Spring, 1897. Tanner's Spring is one of two still-active springs in Central Park. Today it doesn't look like much more than a murky pond or large puddle, but the spring has an interesting 19th-century history. In 1825 free African Americans began buying land in an area between 82nd and 89th Streets and Seventh and Eighth Avenues. The community grew to become Seneca Village and this spring provided the residents with water. The community was evicted in 1857 in preparation for the construction of Central Park. In 1880 the spring got its name when Dr. Henry S. Tanner, a proponent of therapeutic fasting, began a 40-day fast (under observation) with his only nourishment coming from the water at this spring. Local lore then developed that this water source contained some magically concentrated nutrients.

Public School 166 ARCHITECT: C. B. J. Snyder DATE: 1897-99 STYLE: Collegiate Gothic Built in 1897-99, Public School 166 is one of the few remaining nineteenth-century institutional buildings, and one of the oldest extant public schools, on the Upper West Side. The school was designed by New York’s Superintendent of School Buildings, C.B.J. Snyder, who held that position from 1891 to 1923, exerting a tremendous influence on the design and construction of the city’s schools. He created buildings that were inventive, functional, and handsome as civic monuments and is credited with introducing the Collegiate Gothic style (usually associated with universities) to New York’s public school architecture where it was used for over twenty years.

25-23 West 83rd Street, ca. 1911.

The Ardsley, 1928. Built in 1900 and designed by George W. Keister, the ten-story apartment building was a grand apartment house. The rounded bays of the Central Park West facade allowed for excellent views of the Park and for ideal cross ventilation. The individual apartments were massive with six to twelve rooms; some apartments had three bathrooms. Other features included private telephones, electric lighting and individual "refrigeration plants." But the gilded, over the top 19th century style of the building was, by the 1920s, passé. The older Victorian style buildings of Central Park West began to be demolished and in their place, sleek Art Deco style buildings were rising.

127 West 89th Street, unknown date. This theatre, which is for sale, was formerly the Battery Swedish Methodist Episcopal Church

12-16 West 86th Street, ca. 1913. Designed by Alexander Welch, for speculative developers William and Thomas Hall, the row mansions were constructed in 1910. No. 14 (at center) was designed in the neo-Renaissance style, while no. 16 (at right) is neo-Georgian.

161-165 West 83rd Street, 1912. As per the notes on the photograph, these wood-frame homes were demolished in the 1910s to make way for a large apartment building.

West Park Presbyterian Church ARCHITECT: Henry Kilburn DATE: 1889-1890 STYLE: Romanesque Revival The West Park Presbyterian Church is considered to be one of the best examples of a Romanesque Revival style religious structure in New York City. The extraordinarily deep color of its red sandstone cladding and the church’s bold forms with broad, round-arched openings and a soaring tower at the corner of West 86th Street and Amsterdam Avenue produce a monumental and distinguished presence along those streets.

The Ardsley, 320 Central Park West. Door detail, ca. 1990.

The Beresford ARCHITECT: Emery Roth DATE: 1928-29 STYLE: Renaissance The Beresford Apartments, completed in 1929 and designed by Emery Roth, then at the pinnacle of his career as a specialist in apartment house design, is one of the largest and grandest of the apartment buildings along Central Park West. Prominently located at the corner of 81st Street across from the American Museum of Natural History, it takes full advantage of its site, with two monumental facades crowned by corner towers. Executed in brick with limestone and terra-cotta detailing, the Beresford is distinctively ornamented with a sculptural program of late Renaissance inspiration which features winged cherubs, angels, dolphins and rams’ heads, along with elaborate cartouches, festoons, rosettes and finials. Its vast scale and dramatic profile make the Beresford one of the most important elements on the Central Park West skyline, as well as a reminder of the heyday of luxury apartment building in New York.

127 West 89th Street, ca. 1925. Formerly the Battery Swedish Methodist Episcopal Church, 127 West 89th Street, between Amsterdam and Columbus Avenues. This church was remodeled into a motion picture theatre and by 1931 the theatre was boarded up and offered for sale.

El Dorado Apartments, ca. 1920. The history of the El Dorado Apartments is similar to that of its nearby neighbor The Ardsley. The original El Dorado (seen in this photograph) was an eight-story speculative apartment house completed in 1902. Somewhat similar in design to the original Ardsley, the CPW front of the building had large rounded corners to allow for sweeping views of the park and good cross ventilation. In the 1920s the real estate market on Central Park West boomed and a number of the older apartment houses were demolished and replaced. In 1929 investor Frederick Brown bought the first El Dorado and resold the site to Louis Klosk, a Bronx-based developer. The financial crisis that followed would eventually stall the construction and force Klosk to foreclose. The eventual building, finished late in 1931 under new ownership, was a 30-story, twin tower Art Deco building. Designed by Margon & Holder, and their associate architect Emery Roth (who designed the second Ardsley) the large building has terraced setbacks on the towers topped by abstract geometric spires.

By Justin Martin Once Frederick Law Olmsted and his mentor, the British-American architect and landscape designer Calvert Vaux received the nod to proceed with their design for Central Park, the commissioners pressed them to move quickly. By 1858, the issue of a large park in New York had dragged on for many years. Millions had been spent obtaining the land; thousands more had been spent clearing it. To justify all this expenditure, some progress needed to be shown. The plan was to open the park to the public in stages. The board asked Olmsted and Vaux to have certain sections ready by winter so the park could receive its very first visitors, ice skaters. Read this in its original format here

West Drive, Central Park, ca. 1910.

15 West 81st Street, formerly the American Geographical Society Building. The American Geographical Society Building was designed by Howells & Stokes in 1901. For whatever reason the society never seemed able to settle on a location, constantly moving around the city until 1911 when they moved to Audubon Terrace. Today, they are located in Brooklyn. The building pictured in the foreground was demolished in the late 1920s and replaced with an Emery Roth designed apartment building.

39-35 West 89th Street, ca.1915. This series of Renaissance Revival rowhouses was constructed in 1894-1895. The row, from nos.19-39, were designed by Gilbert Schellenger, who designed homes all over the city, including many in the proposed Bedford-Stuyvesant historic district.

Sandhogs are urban miners and underground construction workers who’ve been tunneling through sand, mud, and bedrock for well over a century. They dug New York’s subway, traffic, sewer, and water tunnels, as well as foundations for structures like the Woolworth Building. The term “sand hogs” originated with workers digging the sandy bottom of the East River inside caissons to build the Brooklyn Bridge. Over time, the term expanded to describe any laborer working underground in the City, and became specifically tied to the Local 147 Sandhogs Union. NYC built three deep pressure tunnels through bedrock to carry water throughout the five boroughs. Placing them hundreds of feet underground kept the water supply safely below any utility and subway tunnels, and the depth required laborers who could work under often grueling and dangerous conditions.

The Beresford, 1931 The Beresford was designed by famed architect Emery Roth, who also created the plans for numerous other CPW apartment houses including The El Dorado, The San Remo, and The Ardsley. It was named for the Hotel Beresford, which had previously occupied the lot. Completed in 1929, the building was one of the most prestigious addresses for much of the 20th century. Helen Gurley Brown and her husband lived for three decades in the four-story penthouse that topped one of the three corner towers. She once said," I’m slightly prejudiced, but I think it’s the best apartment in New York." The building has been called home by a number of other famous and infamous New Yorkers, including Jerry Seinfeld, Diana Ross, and mobster Meyer Lansky.

Jewish Center, ca. 1918. While the Upper West Side boasted a number of Jewish congregations in the early decades of the 20th century, most observed a casual prayer environment, or in the case of Congregation Shearith Israel, offered more formal, but foreign services. Two successful clothing manufacturers who moved to the neighborhood, Joseph H. Cohen and William Fischman, looked for but did not find a traditional Orthodox Synagogue. With the religious leadership of Rabbi Mordecai M. Kaplan, the two men founded the Jewish Center in 1918. The new synagogue building, designed by Louis Abramson in a Neo-Classical style, housed not only a main sanctuary. The tall building was an extensive facility that sought to serve not only as a spiritual home, but also a cultural, social, and recreational home for its members.

40 West 86th Street, ca. 1980.

247-249 Central Park West, ca. 1975. Constructed between 1889 and 1890, developer William Noble and architect Edward Angell created a row of nine Queen Anne style homes. The buildings which ran from nos. 241 to 249, were speculatively built, intended for wealthy families. These grand homes facing Central Park spared no expense; they included stained glass, gargoyles, angled staircases, turrets, and balconies. The Real Estate Record & Builders’ Guide described the row as perhaps too whimsical, taking offense at their “giddiness.” Being the corner building, no. 249 (at right) was perhaps the most fanciful of the homes, with a faceted tower topped by a conical tiled cap and false balconies. It was first purchased by by wallpaper manufacturer Frederick Beck and hosted his daughter's extravagant society wedding in 1890. In 1914 it was owned by clergyman Luther Albert Swope and his wife, who came from a wealthy New York family. The home passed to a Swope nephew in 1930 and was sold in 1974. By that time some of the facade had been stripped of its ornamentation, it had been painted (!) white, the interior had been converted to apartments, and all of its neighbors (save no. 247 next door) had been demolished. Around 1990 the paint was striped to work on the facade which had begun to crumble. In 2006 the home was sold for $14.4 million and a conversion back to a single family house was undertaken. Amazingly, though the upper floors have been gutted, much of the original interiors of the lower floors remain intact, including an entirely oak-paneled dining room.

Apthorp Mansion, 1891. The Apthorp Farm was a large plot of land on what is now the Upper West Side of Manhattan (approximately 78th to 99th Streets, from Central Park to the Hudson River). Loyalist and merchant Charles Ward Apthorp purchased parcels and built a mansion in 1764 at what is now 90th Street and Columbus Avenue. It was considered one of the grandest pre-Revolutionary houses in Manhattan. The Hudson River-facing mansion was called "Elmwood" because of the large, mature elm trees that stood nearby. During the Revolutionary War the home was occupied by both sides at various points, a hard fact for the faithful British subject, Apthorp. In the mid 19th century the house and some of the surrounding land became "Elm Park," a beer garden, picnic area, and inn popular among German immigrants. It was also used as a parade ground, where in 1870 a clash between Irish Catholics and Irish Protestants resulted in eight deaths. The home was demolished in 1891, while the original acreage had largely been divided and sold off decades earlier. In 1908 a large apartment house was constructed on the full block between Broadway and West End Avenue and West 78th and West 79th streets. That plot of land had once been occupied by a different home built by Apthorp in 1759 (and sold to someone else less than ten years later). The 20th century apartment building was named for the original landowner.

32 West 88th Street, 1911. Built as a series of buildings on the south side of 88th Street between Central Park West and Columbus Avenue in 1887-1889, no. 32 is one of a few of the buildings to retain the majority of its original features. Designed by Thom and Wilson, the rowhouses here are of a Renaissance Revival style with Romanesque and Gothic Revival features. A number of these buildings were altered in the 1910s and 1920s. They had their stoops removed, new basement entrances created, and some even had their cornices removed as well. No. 32 retains its prominent dogleg front staircase.

241 Central Park West, date unknown. Built between 1930-31 and designed by Schwartz & Gross, the 19-story Art Deco building is clad in brick and cast stone. The architecture firm was well-known for their apartment houses, particularly in Morningside Heights.
