'''The Knickerbocker Hotel''' is a hotel at [[Times Square]], on the southeastern corner of [[Broadway (Manhattan)|Broadway]] and [[42nd Street (Manhattan)|42nd Street]], in the [[Midtown Manhattan]] neighborhood of [[New York City]], New York, U.S. Built by [[John Jacob Astor IV]], the hostelry was designed in 1901 and opened in 1906. Its location near the [[Theater District, Manhattan|Theater District]] around Times Square was intended to attract not only residential guests but also theater visitors.

The hotel is designed, largely in the [[Beaux-Arts architecture|Beaux-Arts]] style, by Marvin & Davis, with [[Bruce Price]] as consultant. Its primary [[frontage]]s are on Broadway and 42nd Street. These facades are constructed of red brick with [[terracotta]] details and a prominent [[mansard roof]]. The Knickerbocker Hotel also incorporates an annex on 41st Street, built in 1894 as part of the St. Cloud Hotel, which formerly occupied the site. The 41st Street facade contains a [[Romanesque Revival architecture|Romanesque Revival]] designed by Philip C. Brown. The hotel contained 300 rooms, a restaurant, a coffee shop, and a roof bar. The original interior design was devised in 1905 by [[Trowbridge & Livingston]], the  scattered remnants of which include an entrance that formerly led from the [[New York City Subway]]'s [[Times Square–42nd Street station|Times Square station]] to the hotel's basement.

The original hotel was home to [[Enrico Caruso]] and [[George M. Cohan]], until it was shuttered in 1920, due to a decrease in business. The building was then converted to offices, becoming known as the Knickerbocker Building; it was the home of ''[[Newsweek]]'' magazine from 1940 to 1959 during which it was called the Newsweek Building. After major renovations in 1980, it became known as 1466 Broadway and was used as garment showrooms and offices. Following another renovation in 2001, it was known as 6 Times Square. The Knickerbocker was added to the [[National Register of Historic Places]] in 1980 and was designated a [[New York City Landmark]] in 1988. It was converted back to a hotel from 2013 to 2015, and restored to its original name.

=== Facade ===

==== Broadway and 42nd Street ====
[[File:Knickerbocker Hotel jeh.JPG|thumb|The 42nd Street (left) and Broadway (right) facades of the Knickerbocker Hotel, seen in 2008. In the background can be seen [[1095 Avenue of the Americas]] and the [[Bush Tower]].|left|alt=The 42nd Street and Broadway facades of the Knickerbocker Hotel, seen in 2008.]]

The Knickerbocker Hotel's Broadway and 42nd Street facades are [[Articulation (architecture)|articulated]] into three horizontal sections: a two-story base, a ten-story shaft, and a three-story mansard roof. The ground and second stories serve as a commercial base and have seen numerous design changes since 1920.<ref name="NYCL p. 5; NPS p. 2" /> The vertical limestone [[Pier (architecture)|piers]] are the only portions of the original design that remain at the base. Originally, a ground-level [[portico]] projected from the center seven [[Bay (architecture)|bays]] of the 42nd Street facade, with seven round arches topped by a [[balustrade]].<ref name="NPS p. 2" /> This portico was removed by 1911.<ref name="NYCL p. 5">{{harvnb|Landmarks Preservation Commission|1988|ps=.|p=5}}</ref> There was a similar portico at the center five bays on Broadway, which was flush with the rest of the facade. The second floor contained round-arched windows.<ref name="NPS p. 2">{{harvnb|National Park Service|1980|ps=.|p=2}}</ref> The Broadway facade originally contained a secondary entrance to the cafe.<ref name="nyt19060218" />

On the third through twelfth floors, the building is clad in red brick with decorative elements made of [[Indiana Limestone]] and [[Architectural terracotta|terracotta]].<ref name="NYCL p. 5; NPS p. 2" /> Some of the limestone and terracotta ornamentation has been replaced with similar-looking concrete.<ref name="nyt20030822" /> Along 42nd Street, the outermost four bays are grouped into slightly projecting "corner pavilions", flanking the center seven bays. The two center bays on each corner pavilion are paired. The Broadway facade is nine bays wide and lacks projecting corner pavilions. Each window is flanked by stone [[quoin]]s. The fourth, sixth, seventh, and eleventh-story windows contain either decorative iron balcony rails or stone balustrades. The [[pediment]]s atop windows on each story are variously made of segmental arches, sculptured decorations, or swans' necks.<ref name="NYCL p. 5; NPS p. 2">{{harvnb|Landmarks Preservation Commission|1988|p=5}}; {{harvnb|National Park Service|1980|ps=.|p=2}}</ref>

A small cornice runs above the fourth story, while more substantial cornices run above the ninth and eleventh stories.<ref name="NPS p. 2" /> At Broadway, the center bay contains an arched pediment above the fourth-story window that interrupts the cornice above it.<ref>{{harvnb|Landmarks Preservation Commission|1988|p=5}}; {{harvnb|National Park Service|1980|ps=.|p=3}}</ref> The ninth story cornice is supported by decorative [[Bracket (architecture)|brackets]] while the eleventh story cornice is supported by [[modillion]]s.<ref name="NPS p. 2" /> All three cornices have lost some of their original decorative elements.<ref>{{harvnb|Landmarks Preservation Commission|1988|p=6}}; {{harvnb|National Park Service|1980|ps=.|p=2}}</ref>

The thirteenth through fifteenth stories are part of the [[mansard roof]], which is clad in green copper. There are also urns at the corners of the roof.<ref name="NYCL p. 5; NPS p. 2" /> Originally, the dormer windows from the mansard roof contained elaborate pediments, although these were likely removed by 1920. The thirteenth floor windows' pediments were either triangular or segmentally arched. The fourteenth floor windows' pediments were round-arched.<ref name="NPS p. 2" /> A penthouse on the fifteenth floor was added between 1908 and 1910 to designs by C. H. Cullen.<ref name="NYCL p. 5" />

==== 41st Street ====
[[File:Times_Sq_Sep_2021_64.jpg|thumb|41st Street facade]]
The 41st Street facade of the Knickerbocker Hotel is eight stories tall and is designed in the Romanesque Revival style, with some ornament in the Beaux-Arts style. The facade is made of [[Buff (colour)|buff]] brick and [[Architectural terracotta|terracotta]].<ref name="NYCL p. 6">{{harvnb|Landmarks Preservation Commission|1988|ps=.|p=6}}</ref> It was intended as a service entrance to the main Knickerbocker Hotel.<ref name="AR p. 630" />

The annex previously contained a second story with three bays of windows, above which runs a classical-style cornice.<ref name="NYCL p. 6" /> When the Knickerbocker was re-converted back into a hotel in the 2010s, the double-height first story was altered for a service entrance that takes up the entire width of the 41st Street facade.<ref>{{Cite web |last=Kramer Levin Naftalis & Frankel LLP, for 1466 Broadway LP c/o Highgate Holdings, Incorporated, owner. |date=February 1, 2011 |title=Appeal pursuant to Section 310(2) of the Multiple Dwelling Law seeking to vary the court requirements under Section 26 of the Multiple Dwelling Law to permit the hotel conversion of an existing commercial building. |url=http://www.nyc.gov/html/bsa/downloads/pdf/decisions/216-10-A.pdf |url-status=live |access-date=March 9, 2021 |publisher=New York City Board of Standards and Appeals |archive-date=August 1, 2021 |archive-url=https://web.archive.org/web/20210801022151/http://www.nyc.gov/html/bsa/downloads/pdf/decisions/216-10-A.pdf}}</ref> The third floor was skipped. The fourth and fifth stories are topped by an arch that spans the entire width of the annex. The sixth through eighth stories are flanked by [[pilasters]], with two bays each on the sixth and seventh stories and three bays on the eighth stories. The attic, on the ninth story, was constructed in 1906 and contains two [[dormer]] windows with triangular copper pediments.<ref name="NYCL p. 6" />

== History ==

=== Construction ===
In 1901, the [[New York City Department of Buildings]] received plans for three hotels, one theater, and fourteen apartment buildings on Times Square.<ref name="NYCL p. 2" /> Among those plans was a 14-story hotel designed by Bruce Price and Martin & Davis, to be built on the site of the St. Cloud Hotel at Broadway and 42nd Street.<ref name="nyt19011016" /> The new hotel, known as the Knickerbocker, was intended as a rival to the [[Hotel Astor (New York City)|Hotel Astor]], also owned by the Astor family.<ref name="NPS p. 4" /><ref name=NY1900/> The Knickerbocker was to be a Renaissance Revival hotel with a similar arrangement to other hotels of the time. In addition to service facilities across two basement levels and dining and banquet facilities on the first and second floors, the Hotel Knickerbocker was planned with 600 suites and 300 baths.<ref>{{harvnb|Hutchins|1902|ps=.|pp=630, 632}}</ref> At the time, the section of Broadway between 34th and 42nd streets was quickly being developed with theaters and hotels.<ref>{{Cite news |date=June 26, 1904 |title=Broadway's Future South of Times Square; Real Estate Movement That Promises to Have Unusual Elements of Strength – Large Plots Awaiting Development |language=en-US |page=17 |work=The New York Times |url=http://timesmachine.nytimes.com/timesmachine/1904/06/26/102418348.pdf |url-status=live |access-date=March 11, 2021 |issn=0362-4331 |archive-date=August 1, 2021 |archive-url=https://web.archive.org/web/20210801022114/https://timesmachine.nytimes.com/timesmachine/1904/06/26/102418348.pdf}}</ref> Consequently, the Hotel Knickerbocker's construction spurred the development of other hostelries nearby.<ref>{{cite magazine |date=November 16, 1907 |title=Changes in Long Acre Square |url=https://rerecord.library.columbia.edu/document.php?vol=ldpd_7031148_040&page=ldpd_7031148_040_00000837 |journal=The Real Estate Record: Real Estate Record and Builders' Guide |volume=80 |pages=799 |via=[[Columbia University|columbia.edu]] |number=2070 |access-date=March 11, 2021 |archive-date=April 3, 2022 |archive-url=https://web.archive.org/web/20220403231553/https://rerecord.library.columbia.edu/document.php?vol=ldpd_7031148_040&page=ldpd_7031148_040_00000837 |url-status=live}}</ref>

A critic for British newspaper ''[[The Daily Telegraph]]'' gave the Knickerbocker a 7/10 rating, saying that the hotel "adds a pinch of sophistication to Times Square.
