Celle is a town in Lower Saxony, Germany. It is the capital of the district (Landkreis) of Celle. The town is located in the southernmost part of the Lüneburg Heath on the banks of the river Aller, a tributary of the Weser. The buildings in Celle’s old town center date back to the 16th century, among them numerous (and some 480 restored) half-timber houses, making Celle an important city for tourism in the southern Lüneburg Heath region. The most impressive building is the ducal palace, Schloss Celle, which was built in 1530 at the site of the former castle. Another major attraction is the Stadtkirche (town church, 1308) with its white tower, from where the town trumpeter blows a fanfare twice a day (an old tradition that was revived as a tourist attraction). Celle has a synagogue built in 1740, one of the few synagogues that survived the Nazi pogrom night of 1938, thanks to its location next to an important leather factory that would have been collaterally damaged.
