This handsome, 15-story apartment building on the northeast corner of Broadway and 75th Street was erected in 1924 and converted to a cooperative in 1989.

The brown-brick building, which is known as Majestic Towers, has 110 apartments and a bandcourse at the 14th floor, quoins at its corners and the sides of its windows on the second and third floors, and a cornice.

It was designed by Schwartz & Gross.

According to the building's website, it was "well-known in its early days as a second home to gangsters, writers, politicians and others who frequented its bordellos," adding that "In fact, that 'life of sin' has much to do with the building's labyrinth of front and back apartment entrances and the multiple interior staircases."

The website has an article by Lisa Jacobs on the building's "dirty little secret":

"If these walls could talk, today's residents would be spellbound by tales of Majestic Towers' dark past and fascinating history. Imagine the Roaring Twenties with its ladies of the night, gangsters, important political and literary figures, bootleggers, police raids, all night soirees, and a portrait of our building, formerly a house of sin, snaps into place like pieces of a puzzle....'The building was designed as a bordello,' said long-time resident Professor James Nassy, who first moved in during the early 60s when a few ladies of the night still lived here. Behind the discreet elegant facade, the most spectacular features of the building lay cached. Multiple hidden stairways and secret doorways give the building an air of mystery and double identity. Its layout was conceived for clandestine behavior and was exactly what attracted one of the most notorious tenants, Polly Adler. Adler ran the most popular brothel in the 20s from a succession of rented apartments on the Upper East and Upper West Sides. The full-fledged madam set up shop at 215 West 75th Street in the late 20s and ran a club-like business where the women were an attraction, but not always the main course. 'Polly's' was more than a brothel. It was a clubhouse. Adler decked out her establishments in luxurious decor, with Persian carpets, expensive furniture, paintings, and walls lined with books. Elite writers and intellectuals who were members of the famous Algonquin Round Table were frequent patrons. Vanity Fair writes Robert Benchley and Dorothy Parker (who went for the ambience of he place) even suggested titles for Adler's library. Benchley was known to spend the night, and reportedly even did some of his magazine writing in the company of her prostitutes. Patrons, including the immensely charming mayor Jimmy Walker as well as mob boss Dutch Schultz, came by for drinks, backgammon and card games as much as for the prostitutes."

According to her entry at wikipedia.org, Ms. Adler opened her first bordello in 1920 and retired in 1944. She attended college when she was 50 and wrote a book, "A House is Not A Home" in 1953 that was made into a movie two years later with Shelley Winters.

She died in 1962.

The building has a roof deck and a bicycle storage room and windowed baths and kitchens. It is pet friendly.
