 The Anglican parish church of St. Michael dates from the 15th century and has been designated by English Heritage as a Grade II * listed building ; its tower used to display a beacon light for ships approaching the harbour . After being caught in a violent storm at sea , Robert Quirke dedicated a ship and its cargo to God 's service , as well as donating a cellar near the quay for prayers to be offered for those at sea . Dating from 1628 and known as the Gibraltar Celler [ sic ] , it is now the Chapel of St Peter . Quirke also donated money from the sale of the ship and its cargo to build almshouses .
