St Canna Church is believed to date from the 12th or 13th century. It is said to have been rebuilt in 1820, but by 1875 it was described as being deserted and full of insects, snails and weeds. A publication four years later stated that the church was 'about to be removed' because the population had moved away from the area.
The church is said to have been extensively rebuilt in 1856 with more work being done in 1869. Many of its original features were destroyed during this time period. A school room was added to the structure in 1881. In 1909 a pre-Norman cross was discovered in the garden of the church rectory. The cross is believed to date from the ninth century; it was not intact when found but was pieced together.
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.
