Herald Towers, formerly the Hotel McAlpin, is a residential condominium building on Herald Square, along Broadway between 33rd and 34th Streets, in the Midtown Manhattan neighborhood of New York City. Constructed from 1910 to 1912 by the Greeley Square Hotel Company, it operated as a short-term hotel until 1976. The building was designed by Frank Mills Andrews in the Italian Renaissance style and was the largest hotel in the world at the time of its completion, with 1,500 guestrooms. The hotel was expanded in 1917, when Warren and Wetmore designed an annex with 200 rooms.
