Freshwater spring at the Tiemann & Company Paint & Dye Works, 1897. In the early decades of the 19th century Manhattanville, in West Harlem, was a sleepy area of farms and a few out-of-the-city mansions. In 1832 a freshwater spring was discovered near Broadway and 125th Street (then called Manhattan Street). With plentiful water for production operations businessman, Anthony Tiemann, moved his Tiemann & Company Paint & Dye Works uptown, settling on a large plot at 560 Riverside Drive. The company, founded in 1804, was one of the earliest color works in America. This move began the slow but steady industrialization of Manhattanville. Tiemann retired a few years after the move uptown and his son Daniel F. (who was later Mayor of New York 1858-1860) took over control of the business. About 50 German men and their families had moved to Manhattanville to work in the factory when it was established here. Within the first decade, the factory grew to cover 40 lots with more than 120 workers. These Germans helped to create a prominent German community uptown. Following a number of fires in the 19th century (dye making materials + a spark= bad news), the factory was sold in 1902. The young boy in the photo is playfully shooting water out of Tiemann's spring situated on the factory property.

We are looking east along West 123rd Street in this view from Amsterdam Avenue. This is the northern boundary of the park. We see the Block House No. 4, a remnant fortification built but never used to defend the city in the war of 1812. PS 36 now sits on this same outcropping. One of the other block houses built at this time still survives in the north woods of Central Park.

Block House #4, ca. 1905. Block House #4 sat on the massive glacial rock outcropping at 123rd Street and Amsterdam Avenue. It was one of a series of stone defense fortifications constructed around the War of 1812. Despite the preparation for the perceived threat of British invasion, the British never made it to Manhattan during the war. The ruins of Block House #4 remained on the outcropping until the 1960s when Public School 36 was constructed on the site. The sections of the school where built directly on the large rock, which can still be seen on the 123rd Street side. A single block house survives in the northern section of Central Park; it is also situated on a large rock outcropping.

The Riverside Drive Viaduct was built in 1901. The 50-foot tall elevated roadway is an extension of Riverside Drive. The Drive splits into two paths at the terminus of Riverside Park which converge at the entrance to the Viaduct. Aside from a masonry approach on both the north and south entrance, the structure is entirely steel. At the time of its construction, the girders over 125th street were the largest ever built. F. Stuart Williamson was the chief engineer of the project, which was regarded as a civic monument. The Scientific American referred to Riverside Drive as "a continuous drive of ten miles along the picturesque banks of the Hudson and Harlem Rivers."

Construction on the Manhattan Valley Viaduct of the IRT Broadway-Seventh Avenue Line, at the future site of the line's 125th Street station; July 10, 1903. Today, 125th Street is the southernmost of four above-ground stations in Manhattan. The viaduct was added to the National Register of Historic Places in 1983.

Another view of the Block House No. 4 and the exposed manhattan schist face where West 123rd Street was cut through at the northern termination of the park. As we’ve seen in this story, the geology and resulting dramatic topography of a ridge of Manhattan Schist is a defining feature of Morningside Park. In fact, it’s only due to the daunting nature of this rock that Andrew Haswell Green decided to not extend the east-west street grid through this part of Manhattan and instead called for a park to be designed and constructed on this land.

656 West 125th Street, c. 1941 This white-bricked triangular building opened as a Shell Gas Station in 1920. By 1978, the building was repurposed as a reincarnation of Harlem's Cotton Club which operated from 1923 to 1940. The original Cotton Club, located on Lenox Avenue and 142nd Street, was a segregated establishment where an all-white audience watched black dancers, comedians, and musicians. Acts reproduced entertainment that cast performers as exotic, savage, or "darkies" from the plantation south. Artists such as Fletcher Henderson and Duke Ellington enjoyed increased popularity after performing at the Cotton Club, though Langston Hughes criticized it as "authentic black entertainment to a wealthy, whites-only audience." The club closed in 1940. When the new club opened at this location, Billboard magazine wrote: "if after an evening at the Cotton Club anyone fed up with the elegance can walk to the subway and pass one of Manhattan's most blighted and desolate areas."

ST. JOSEPH’S CHURCH, MANHATTAN Address: 401-403 West 125th Street Architect: Constructed: 1860 Church of St. Joseph of the Holy Family is the oldest church in Harlem and the oldest church north of 44th Street, completed in 1860. The modest Romanesque structure was originally built for German immigrants, and was expanded in 1889 by the Herter Brothers.

Jacob Schieffelin gave the land for St. Mary's Episcopal Church. The parish was formed to minister to the poor in 1823 by fashionable St. Michael's Church in Bloomingdale at the north end of the present-day Upper West Side, where Schieffelin served as a vestryman. By the 1830s, St. Mary's had the distinction of being the first "free" Episcopal church in the nation, charging no annual fee for pew rental. The rectory of St. Mary's Church at present-day 521 West 126th Street was built about 1840 by architect Robert Oughton. It survived a turn-of-the-century fire that destroyed the church. The church was quickly replaced-and enlarged-by the Schieffelin family (newly enriched through an alliance with the Vanderbilts). With a long history of serving the poor and the working class, it would survive in a changing Harlem where other churches failed.

St. Mary's Episcopal Church, 1931. The parish of St. Mary's dates to the early 19th century when Manhattanville was its own town. Organized in 1823, the first church building, a simple wood-frame chapel with a short steeple, was constructed in 1824-1826. It was once described, "St. Mary's was white and severely plain on the outside and square and bare within." In 1831 this parish became New York's first Episcopal church to abolish pew rentals, a practice of raising funds that often created a hierarchy among the community. The first structure survived until the turn of the century, but then succumbed to the oft destroyer of wood-frame buildings: fire. A new neo-Gothic church was constructed in 1908-1909 by Theodore E. Blake, in association with Carrère & Hastings. The simple church with herringbone brickwork trimmed with concrete, was a sort of departure for all architects involved. Blake worked more commonly on homes, especially later as a individual architect, while Carrère & Hastings (Blake was long Hastings' assistant) were usually involved in much more ornate structures.

527 Riverside Drive, ca. 1915. This lavish apartment house called The Ardelle no longer stands. Built in 1909 or 1910 by architects Radcliffe and Kelly, the advertisement for the building notes its proximity to the subway, surface transportation, and nearby educational institutions. It also notes the presence of "plenty of closets" suggesting that concerns about closet space are not only a contemporary problem for New Yorkers.

The Jewish Theological Seminary building is made up of three interconnected wings in the Colonial Revival style. The building’s most pronounced feature is its tall entry tower, which features a Lee Lawrie–sculpted representation of the burning bush above its grand arched entryway.

"622 West 131st Street, south side, between Broadway and Twelfth avenue. This is a three-story frame house. The first story has a brick front and the two upper stories are of wood, 1932." This brick and wood-frame structure survived until sometime between 2011 and 2013 (when it disappears from Google streetview).
