Excavations in the mid-1990s revealed remains of Regensburg's once-thriving 16th-century Jewish quarter, along with Roman buildings, gold coins and a Nazi bunker. The subterranean Document Neupfarrplatz only provides access to a small portion of the excavated area, but tours feature a worthwhile multimedia presentation (in German) about the square's history. Back up above, on the square itself, a work by renowned Israeli artist Dani Karavan graces the site of the former synagogue.
