The St. Thomas Synagogue has been in continuous use under thee American flag longer than any other synagogue.

The St. Thomas Synagogue was declared a National Historic Landmark in 1997. At that time it was stated: “Saint Thomas Synagogue, built in 1833, is the second-oldest synagogue (building) and longest in continuous use now under the American flag. The synagogue, fourth on its site, was built to house a congregation founded in 1796 by Sephardic Jews who had come to the Caribbean Basin to finance trade between Europe and the New World. The congregation reached its zenith in the mid-19th century, declined in the late 19th and early 20th centuries with the fortunes of the Danish Virgin Islands, and grew again in the late 20th century.”
