It took nearly 400 academics and conservation experts from all over the world ten years to re-create the ornate roof of an ancient synagogue from the town of Gwoździec. Decorated with paintings done by hand using traditional methods similar to those of the original, the roof proves an extraordinary example of Jewish sacral architecture in Poland. The original synagogue is no longer standing, and the replica was finally installed on the 12th of March 2013, viewable from several levels of the main gallery.
