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. ― Google
