St Mary's Church, Llanfair-yng-Nghornwy is a medieval parish church in the north-west of Anglesey, north Wales. The date of foundation of the church, which is in the village of Llanfair-yng-Nghornwy, is unknown, but the oldest parts date from the 11th or 12th century. It has twice been enlarged: in the 15th century, when the chancel was rebuilt, and in the 16th century, when a chapel was added to the south of the chancel, separated by three arches. The tower at the west end is from the 17th century. A south porch of unknown date has been converted into a vestry, and the church is now entered through the tower.
The church is still used for worship by the Church in Wales, one of nine in a combined parish, although as of 2013 there has not been an incumbent priest since September 2009. People associated with the church include James Williams, a 19th-century rector who was awarded a gold medal for his efforts to save lives at sea, and his great-grandson, the artist Sir Kyffin Williams. Both are buried in the churchyard.
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.
