The capital of St Vincent is a lively port and market town on the southern coast. The town contains 12 small blocks with a variety of shops and a busy dock area, which is the center of commerce for the islands. The Saturday morning market, comprising many stalls piled high with fresh fruit and vegetables, brings everyone to town. In the center of Kingstown, St Mary’s Roman Catholic Cathedral, built of grey stone, is a graceful combination of several European architectural styles displaying Romanesque arches, Gothic spires and Moorish ornamentation. Its architecture has led Kingstown to become known as the City of Arches. The ruins of Fort Charlotte overlook a 180m (590ft) ridge north of town and offer a magnificent southward view of the Grenadines. The oldest Botanical Gardens in the Western hemisphere occupy 8.1 hectares (20 acres) to the north of Kingstown and contain a display of tropical trees, blossoms and plants, including a breadfruit tree descended from the original one brought to the island in 1765 by Captain Bligh.
