St. Mary's Island: A Tidal Retreat in Penzance Guide
St. Mary's Island, also known as Chapel Rock, is a small tidal island located just off the coast of Penzance in Cornwall. Connected to the mainland by a causeway that is submerged at high tide, this unique location offers a tranquil escape and stunning views of Mount's Bay. Explore the island's natural beauty, discover its historical chapel, and enjoy the refreshing sea air. The island's history is closely linked to its chapel, dedicated to St. Mary. The chapel dates back to the 15th century, although it may have been built on the site of an earlier religious structure. It served as a place of worship for local fishermen and seafarers. Over the centuries, the chapel fell into disrepair, but it has since been restored and is now a popular landmark. The island itself has also been used for various purposes, including as a quarantine station and a signal station. Visitors can walk across the causeway to St. Mary's Island at low tide and explore the chapel, enjoy the views, and search for marine life in the rock pools. The island is a haven for seabirds, making it a great spot for birdwatching. Be sure to check the tide times before visiting, as the causeway is only accessible for a few hours each day. While St. Mary's Island doesn't have its own culinary tradition, Penzance offers a wide variety of restaurants and cafes serving fresh seafood and Cornish specialties.
