The present St Cadoc Church was built in the 13th century and is believed to have replaced an earlier church within the manor of Landimore. Restoration was carried out on two occasions in the 19th century and again in 1934. The font may have been salvaged from the earlier church which was abandoned because of the encroaching sea.
The church has a saddleback roof with a defensive intent. The interior of the church contained medieval wall paintings, including scriptural quotations and vine-leaf patterns, but these were destroyed during the Victorian era. Eighteenth-century maps show the church in its present location, near a mill, which went out of use in the 19th century, and 'Great House', which was demolished at a similar date.
In the 1840s, Rev W. L. Collins had the original pews removed, and installed a new window, which was itself replaced during the restoration of the mid-1870s.References:
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
