Denbigh Friary (also known as Henllan Friary) is a ruined monastic religious house situated approximately 1.6 km east of Denbigh. Founded in 1343-50 (or before 1289), the friary was dedicated to St Mary, and was a Carmelite community. The English Benedictine abbot, Robert Parfew was involved in the 18 August 1538 surrender of the Carmelites of Denbigh Friary. During the Dissolution, some of the buildings were turned into houses, while wool was sold in the church. The 14th century building has been in ruins since an 1898 fire. The ruins are mostly from the 13th and 15th centuries, and include parts of a choir, a gable end, and nave walls.
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.
