The Derek Walcott Square is at the heart of the St. Lucia’s capital, Castries. It is named after the Honourable Derek Walcott, the St. Lucian author who, in 1992, won the Nobel Prize for Literature. There is a monument to St. Lucia’s war dead, and a large Samaan tree, known locally as the Massav tree. It is said to be over 400 years old. At the eastern end of the square is the Cathedral of the Immaculate Conception, the illustrations on the interior walls and the altarpiece are the work of local artist Dunstan St. Omer. The Central Library is on the western corner of the square.
