St Thomas à Becket Chapel was constructed in 1180 and dedicated to St Thomas Becket. It commanded fine views of the Haven estuary, situated on the north bank in open space. Along with two other chapels, now disappeared, at Herbrandston and St Anne's Head, it functioned not only as a Catholic place of worship, but also as a Beacon Chapel, or lighthouse to sailors. The chapel enjoyed a dependent relationship with the nearby Pill Priory. By the 17th century the structure was in ruins, when it was occupied by Parliamentarian forces in 1644. It later acquired a function as storage for the battery located on the Rath.
In the twentieth century, it had become used as a pigsty and stable. In 1930, £1,000 was raised, and the building was reconstructed, work completed in 1938. It was re-consecrated as an Anglican chapel of ease. It is built of rubble stone with a graded slate roof, small nave and chancel, both with pointed barrel vaults. The interior is simple with plastered vaults, small niches each side in chancel and a curved rood beam with rood. The nave south facing windows have stained glass of 1935 and 1939 to Sir Hugh Thomas of Castle Hall. In 2012 it was privately sold, in spite of local opposition.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
