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:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
