St Beuno's Church, Aberffraw is a 12th-century parish church in Anglesey, north Wales. A church was established in Aberffraw in the 7th century by St Beuno, who became the abbot of Clynnog Fawr, Gwynedd. St Beuno's may have been used as a royal chapel during the early Middle Ages, as the princes of Gwynedd had a court in Aberffraw. The oldest parts of the church date from the 12th century, although it was considerably enlarged in the 16th century when a second nave was built alongside the existing structure, with the wall in between replaced by an arcade of four arches. Restoration work in 1840 uncovered a 12th-century arch in the west wall, which may have been the original chancel arch or a doorway to a western tower that has been lost. The church also has a 13th-century font, some memorials from the 18th century, and two 18th-century copper collecting shovels.
The church is still used for worship by the Church in Wales, one of four in a combined parish. As of 2013, the parish is without an incumbent priest. St Beuno's is a Grade II listed building, with elements including the unusually fine 12th-century arch.
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.
