Koper, Slovenia


Originally built on an island surrounded by swampland that was later drained, Koper was known as "Goat's Island" when it was under Venetian rule. Today the once fortified Old Town of Venetian-influenced Koper has retained much of its grand architecture from the 15th to 18th centuries. The Praetor's Palace, a blend of Gothic and Renaissance styles, proudly rises above the gray limestone main square. Nearby the Postojna Caves are the most popular underground attraction in Europe, and the Predjama Castle was carved out of a limestone cliff.
