Fürstenhof
The home of the former dukes of Mecklenburg stands next to the Marienkirche. It's an early-16th-century Italian Renaissance palace with touches of late Gothic. The facade is a series of fussy friezes depicting scenes from the Trojan War, and while it's impressive, you'll have to make do with the exterior; the building, which now operates as a courthouse, is not open to the public.
