Neptune. Originally a Gothic Franciscan church built in the 13th century, the 'Dieta Istriana' hall was remodeled in the Baroque style in the 18th century. The region's largest city Pula has one of the best preserved amphitheatres in the world, which is still used for festivals and events. It is surrounded by hotel complexes, resorts, camps, and sports facilities. Nearby is Brijuni national park, formerly the summer residence of late Yugoslav president Josip Broz Tito. Roman villas and temples still lie buried among farm fields and along the shoreline of surrounding fishing and farming villages. The coastal waters offer beaches, fishing, wreck dives to ancient Roman galleys and World War I warships, cliff diving, and sailing. Pula is the end point of the EuroVelo 9 cycle route that runs from Gdańsk on the Baltic Sea through Poland, Czechia, Austria, Slovenia and Croatia. The town of Rovinj contains well-indented coastal areas with a number of small bays hidden within dense vegetation, open to naturists. Although the beaches are not specified as naturist, naturists frequent them. The interior is green and wooded, with small stone towns on hills, such as Motovun. The river Mirna flows below the hill. On the other side of the river lies Motovun forest, an area of about 10 square kilometres in the valley of the river Mirna, of which 280 hectares (2.8 km2) is specially protected.
