St. Ann's Warehouse is a performing arts institution in Brooklyn, New York City. Formerly the Church of St. Ann and the Holy Trinity on Montague Street, in 1980 the site was converted into a venue for classical music. Initially known as Arts at St. Ann's, proceeds from the stage's performances were used to aid in renovating the building. St. Ann's Warehouse moved to the historic Tobacco Warehouse in Brooklyn Bridge Park in 2015.
