Often overlooked, doors are perhaps the most important feature of a building. They are the means by which we escape the often crowded and chaotic streets of the city. Every building has one (well, maybe except for the Raymond Street Jail which was accidentally constructed in 1836 sans front door), but some outfit this largely utilitarian feature with more panache than others. This collection highlights some the city's loveliest historic doorways, from the simple but classic columns of early 19th century Federal rowhouses to the gloriously geometric brickwork of Art Deco apartment houses, and everything in-between.

"Egyptomania," a kind of feverish obsession with ancient Egypt, had spread throughout Europe and America after Napoleon's campaign in Egypt ended in 1802. By 1922, this craze was renewed after the discovery of Tutankhamun's tomb. Take a tour of some of New York's own artifacts that reference both Egyptian and Assyrian art.

The Madison Belmont Building, 181 Madison Avenue (also variously known as 183 Madison Avenue, 40 East 34th Street, 44-46 East 34th Street), ca. 1990. Built in 1924 “as an office and showroom space for silk companies in the developing Silk District of mid-town Manhattan,” per the Landmarks Preservation Commission, the Madison Belmont was among the first buildings in the city to incorporate Art Deco design elements. Architects Warren & Wetmore, along with the Cheney Silk Company, the first major tenant, hired Edgar Brandt to design the entrances and display windows — areas where Art Deco influences are most clearly pronounced. Here, Brandt’s iron and gilded bronze and gold transom design employs a “frozen fountain” effect, a common Art Deco motif.

Madison Belmont Building, First Floor Interior ARCHITECT: Warren & Wetmore DATE: 1924-25 STYLE: Eclectic Revival The Madison Belmont Building was constructed for the Cheney Brothers Silk Company, the country’s largest silk mill at the time, when this area was briefly known as the Silk District. Its overall Renaissance Revival style is accented by prominent Art Deco elements, and was one of the first buildings in the United States to incorporate such motifs. Its elegant iron and bronze framing at the lower three floors and entrances was designed by Edgar Brandt, a pioneer of the Art Deco style in Paris. The building was designated both an Individual and Interior Landmark in 2011. This interior was designed in the Eclectic Revival style. The exterior of the building combines traditional, classically inspired designs with modernist elements, and the interior lobby was designed using traditional motifs inspired by ancient Greece, Rome, and Egypt that include figures of gods and goddesses, mythological beasts and wall frames with lotus leaves suggesting Egyptian antecedents. The lobby has a large amount of metalwork, including applied ornamental figures, wall frames, light fixtures, doors and mail and fireboxes, and it has a very strong sense of luxury and elegance, contributed by the richness of the marble walls, the travertine floors, the decorative bronze figures and doors and the painted, vaulted ceiling.

Today’s Madison Square North neighborhood reflects successive waves of development, the earliest dating to the year Madison Square Park was created—1847. Until very recently, the neighborhood comprised almost exclusively buildings that pre-date 1930. From the park’s opening through the 1920s, Madison Square North evolved from being a fashionable residential enclave to an entertainment district of hotels, clubs, restaurants and theaters, to a commercial hub of offices and mercantile loft buildings. Examples of each are still prominent today, often in startling juxtaposition. The 19th century saw a northward development trend, as new residential neighborhoods were established in response to growing commerce to the south. This pattern repeated itself numerous times up the length of Manhattan. From roughly 1850 to 1865, Madison Square North was fashionable with the city’s elite. Such boldface families as the Stokes, Livingstons, Vanderbilts, and Stewarts (of A.T. Stewart department store fame) were residents. Rowhouse construction, largely built in the popular Italianate style, began first along Broadway and spread to the side streets. Extant rowhouses from this period include two on West 24th Street and four on West 29th Street. After the Civil War, the neighborhood became host to a number of theaters, restaurants, men’s clubs and hotels. The trailblazer in the latter category was the Fifth Avenue Hotel, completed in 1858 on the northwest corner of 23rd Street and Fifth Avenue. The hotel was a social, cultural and political hub until its closure in 1908, at which point it was replaced by the commercial structure at 200 Fifth Avenue. Many hotels also functioned as “bachelor flats” or “apartment hotels” for extended stays. One of the city’s first apartment houses, constructed in 1872 after designs by the noted New York architect George B. Post, still stands at 251 Fifth Avenue. The prevalence of entertainment and commercial ventures on Broadway made it a bustling night-life district. Thus, beginning in the 1890s, Broadway from about 13th to 45th Street became one of the first thoroughfares to be illuminated by electric street lamps and billboards, leading to its lasting moniker “The Great White Way.” By the 1890s and early 1900s, industries including photography, architecture, construction and banking planted roots in the area, constructing commercial high-rises designed in styles such as Gothic Revival, Beaux-Arts and Art Deco. Many of these buildings were also constructed for the wholesale garment industry to initially support the Ladies’ Mile shopping district to the south, which, until they moved to Herald Square in the early 1900s, was home to the R. H. Macy & Co. and B. Altman & Co. department stores. The neighborhood’s growth was spurred on by nationwide industrial trends for ready-to-wear clothing, and later, wholesale household décor. This period of prolific development left a lasting impact, as mercantile loft buildings remain the area’s architectural hallmark. In 2001, the Landmarks Preservation Commission designated the Madison Square North Historic District, 96 buildings from roughly 25th to 29th Streets between Sixth and Madison Avenues. Community members and preservationists are advocating for an extension to the district, to encompass roughly 374 buildings from 23rd to 34th Streets and Sixth to Park Avenues. This area includes the surviving buildings of Tin Pan Alley on West 28th Street, where the American popular music publishing industry was headquartered from roughly 1890 to 1910.
