Most people don't think of Halle as a particularly pretty city. They are right in that it is still a little gritty, but that's part of the charm. And, if you scratch the surface, it's an interesting place.
Halle has a surprisingly good collection of museums making it worth a visit, including the Händel Haus, birthplace of its most famous son, and the Landesmuseum für Vorgeschicht (State Museum of Prehistory), which houses the famous Sky Disk of Nebra. There's even a museum devoted to The Beatles, though its doubtful any of the Fab Four ever stepped foot in the city.
Add to it two universities, a renowned Renaissance cemetery, and the impressive ruins of Burg Giebichenstein - It's no wonder Halle is known as the Cultural Capital of Saxony-Anhalt.
Plus, they have the ultra-sweet Halloren chocolates, one of my favorites from the region.
