The entrance to the original building was on Synagogue Lane, now Serfaty's Passage. Following its destruction in the storm of 30 December 1766, a larger synagogue was rebuilt at the same site in 1768, but with an entrance on Engineer Lane. The second building was also destroyed during attacks by the Spanish on 17 May 1781. A third building was constructed after the conclusion of the Great Siege of Gibraltar. In 1812, that version of the synagogue was damaged by fire and had to be partially rebuilt. The current vaulted ceiling of the synagogue dates from that 1812 renovation. The synagogue at 47/49 Engineer Lane has colourful tiles, marble floors, wrought iron spindles, and wooden furniture. The Great Synagogue not only remains active; it is still Gibraltar's principal synagogue.
