Our Lady of the Rocks was built up by seamen who, for 450 years, dropped a stone into the water on every safe return, the fašinada ceremony still happens each July. Kotor's Venetian walls climb 260m up the mountain behind it. UNESCO World Heritage since 1979. Anchorage: A near-landlocked double bay with total shelter, one of the safest harbours in the Mediterranean. Hazards: No site-specific hazards noted, brief normally. Mehr
