in 1858, and the cathedral opened in May 1879. The cathedral is the most ambitious essay in Gothic that the revival of the style produced and is a mixture of German, French, and English Gothic influences. Another of the prominent buildings Renwick designed was the Corcoran Gallery of Art (now home to the Smithsonian's Renwick Gallery), in the Second Empire style, in Washington D.C. (1859–1871). Other commissions included the first major buildings on the campus of Vassar College in Poughkeepsie, New York (1861–1865), including the Main Hall (1860); Saint Bartholomew's Church (1871–1872) at Madison Avenue and 44th Street in New York City (now demolished); All Saints' Roman Catholic Church (1882–1893) in Harlem in the Victorian Gothic style; and many mansions for the wealthy of the area, including the Peter Aims-Aimes house, "Martinstow", in West Haven, Connecticut. Renwick is revered in Ipswich, Massachusetts, as the architect who designed Ascension Memorial Church, whose cornerstone was laid in October 1869. Renwick also designed the first chapter house of St. Anthony Hall/Delta Psi, the secret fraternal college society which was founded at Columbia University in 1847. Even though the 1879 structure at 29 East 28th Street is marred now by a street level storefront, in 1990 Christopher Gray wrote in the New York Times that "Old photographs show a high stoop arrangement with the figure of an owl on the peaked roof and a plaque with the Greek letters Delta Psi over the windowless chapter room. In 1879, The New York Tribune called it French Renaissance, but the stumpy pilasters and blocky detailing suggest the Neo-Grec style then near the end of its popularity." In 1899 the fraternity moved to a new chapter house on Riverside Drive and for a few years the original building was kept as a clubhouse for graduate members. At that time a newspaper account described it as a "perfect Bijou of tasteful decoration". Among his other designs were banks; the Charity and Smallpox Hospitals on Roosevelt Island; the main building of the Children's Hospital on Randall's Island; the Inebriate and Lunatic Asylums on Wards Island and the former facade of the New York Stock Exchange. Renwick was also supervising architect for the Commission of Charities and Correction. A small group of Renwick's architectural drawings and papers are held by the Avery Architectural and Fine Arts Library at Columbia University. Renwick was also the designer of the bell tower of
