Bevis Marks Synagogue
This is Britain's oldest synagogue still in use and is certainly its most splendid. It was built in 1701, after Jewish people, having been expelled from England in 1290, were allowed to return under Cromwell in 1656. Inspired by the Spanish and Portuguese Great Synagogue of Amsterdam, the interior is embellished with rich woodwork, seven hanging brass candelabra (representing the seven days of the week), and 12 trompe-l'oeil wood columns painted to look like marble. The magnificent Ark, which contains the sacred scrolls of the five books of Moses, is modeled on contemporary Wren neoclassical altarpieces, with oak doors and Corinthian columns. In 1992 and 1993 the synagogue was seriously damaged by IRA bombs, but it was subsequently completely restored. It's closed to visitors during Jewish holidays, so check the website before visiting.
