Rostock
Rostock is a city straddling the Warnow River on the north coast of Germany. It's known for Rostock University, founded in 1419. Rostock Botanical Garden has an arboretum and alpine gardens. In the old town, the Gothic St. Mary's Church features a 15th-century astronomical clock. Nearby is the cobblestone Neuer Markt main square and Rathaus (town hall), which mixes Gothic and baroque styles.
