under heavy use, and in 1942 the terminal itself was demolished. In the late 1980s, boat enthusiast John Krevey converted an old railroad barge on the Hudson River to a floating jetty called Pier 63. A restaurant was opened on the pier. The lightship Frying Pan and the fire vessel John J. Harvey were also originally moored to Pier 63, with both listed on the National Register of Historic Places. In 2007, the barge was moved to Pier 66 on 26th Street. Historical architecture On January 1, 1825, the New York House of Refuge, a jail for juvenile delinquents, opened on Broadway between 22nd and 23rd Streets. The jail housed prisoners up to 16 years old who were serving long jail sentences, including boys who were being imprisoned until at least age 21 and girls until at least age 18. During the first 10 years, the jail held 1,120 prisoners. In 1854, the prison moved to Randall's Island in the East River. A collection of four-story houses called London Terrace was built on the block bounded by 23rd Street, 24th Streets, Ninth Avenue, and Tenth Avenue in 1845. London Terrace was rebuilt in 1930, with the houses being replaced with 14 apartment buildings that each had sixteen to eighteen floors. The new complex had a total of 1,670 apartments, housing 5,000 total residents. At the time of construction it was the largest residential complex in the city. In 1857, the merchant Amos Eno bought a land parcel at the intersection with Fifth Avenue and 23rd Street. He built the luxury Fifth Avenue Hotel on this site by 1859. The six-story-high structure, which was designed to accommodate 800 guests, became the largest hotel in the world at that time. The hotel served as the headquarters of the Republican Party and was used by Presidents Ulysses S. Grant and Chester A. Arthur. When the Prince of Wales, Edward VII, visited the hotel in 1860, the commercial appeal of the adjacent neighborhood was greatly increased. The area bounded by 14th and 23rd Streets between Sixth Avenue and Broadway was soon dubbed Ladies' Mile. In 1908, the hotel was demolished and replaced by the Toy Center. By about 1860, Irish immigrants had displaced African-Americans living in Five Points, the latter of whom later resettled all over Manhattan. A thousand African-Americans eventually settled in an area bordered by 23rd Street on the south, 40th Street
