La Toc Battery is an old fort previously garrisoned by British Colonial Forces. Today it is an historical site, with stone walls, secret underground passages, and provides visitors with a glimpse into a past world. There were 60 surrounding forts protecting the valuable coaling harbour at Castries, of which La Toc is the best preserved. It was completed in 1888 and in use until 1905. It was originally built by the British to repel attacks from the United States on harbour.
