Castries is one of the most beautifully situated Caribbean cities. Surrounded by hills, its large, safe harbor at the head of a wide bay is a constant hive of activity. Castries is a major port of call for cruise ships, which dock at Pointe Seraphine. The spacious Derek Walcott Square features the 19th-century Catholic Cathedral standing in the shade of a 400-year-old samaan tree. There is also a colorful, bustling market. Morne Fortune, ‘hill of good luck’, affords the visitor the chance to inspect the fortification which defends Castries. It also provides a magnificent panorama of the city and the surrounding area.
