The remains of the Great Synagogue and the mikveh (ritual pools) building are located in the Old Town of Vilnius. The exact date of the synagogue’s construction is unknown. Historians believe that it was built after King Vladislovas Vaza granted a privilege to set up a Jewish quarter in Vilnius in 1633. The architect of the synagogue is unknown.
The Great Synagogue was one of the largest Jewish religious institutions in Eastern Europe. It was known as an important Jewish spiritual and educational centre that gave Vilnius the name of Jerusalem of the North. The synagogue was 25 metres long and just over 22 metres wide and 12 metres high. Since it was forbidden for a synagogue to be higher than nearby Christian churches, the structure was dug two metres into the ground. The size and splendour of this Jewish house of worship are said to have surpassed all the synagogues built in the Polish–Lithuanian Commonwealth. Some historical sources say that it could accommodate up to 5,000 people.
Faded Hebrew inscriptions on the buildings of the former Vilna Ghetto, memorial plaques and monuments bear witness to the history of Jewish spirituality and science. Archaeologists have unearthed, among other things, the bases of two pillars of the Bimah, the raised platform from which the Torah was read, and the sites of two mikvahs (ritual baths), as well as the huge outer back wall and part of the floor of the Great Synagogue.
