Castries is the capital city and port of the Antilles island of St. Lucia. With a population of around 65,000 it is the island's largest city and lies between the Caribbean Ocean and the green hilly hinterland. It is the starting point for trips on the island of St. Lucia. There are almost no historical sights left in Castries, since the many wooden houses have burned down over the course of the last few decades. The Cathedral of the Immaculate Conception at Columbus Square and the Government House are well worth seeing. The best time to take a stroll around the town is on Saturday mornings, when the market stalls are set up at the deep-sea port of The Carenage. Duty free shopping is available at the Point Seraphine shopping centre. To the North-East of Castries lies the Vigie Peninsula, where tourists can enjoy the modern holiday village at the beach.
