Rostock is well worth a visit.
Was in it for a day a few years ago. During WW2, British bombers "accidentally" overshot their aircarft factory target and started the world's first firestorm in the small town.
The citizens realised the town was lost, but went to the church and doused the medieval structure in water all night to save it.
After the war, when the DDR came into being, one would imagine that the town would have been rebuilt in the best Stalinist style of concrete architecture.
But no!
People with taste and an eye for beauty were let loose, and the place is beautiful beyond words.
