Saint Lucia's busy commercial capital surrounds a deep harbour, with many government offices, banks and private companies based in the Castries River basin and surrounding hills. More than half of the island's population live in and around the city, making it a bustling hub of activity day and night.

Visit colourful Castries Market to experience what National Geographic calls one of the top ten food markets in the world; enjoy waterfront vistas from restaurants at Pointe Seraphine or La Place Carenage, the islands two duty free shopping destinations; take a ride to Vigie Lighthouse and see Castries from a bird's eye vantage point.

Castries is also the cultural centre of the island, and a short walk from the harbor takes visitors to the cathedral of the Immaculate Conception with its painted murals by the late Sir Dunstan St. Omer. The cathedral is located on Sir Derek Walcott Square, named in honour of Saint Lucia's Nobel Laureate, whose family home on nearby Chaussee Road has been restored to offer visitors a glimpse into this revered poet's early life.
