Monkton Old Hall is a Grade I listed building in Pembroke. While the chimney is of Norman architecture, the rest of the building dates from the 14th century and it underwent restorations in the late 19th and early 20th centuries.
The building was originally a guesthouse for Monkton Priory, located nearby. The current building mostly dates from the 14th century, but the chimney is of earlier construction in the Norman architectural style. After the dissolution of the Monasteries, the building was split up into multiple tenements. J.R. Cobb began a restoration in 1879, as it had been reduced to a ruin consisting of an empty shell. These renovations included the addition of the present roof.
Further modifications took place post-1933, with the addition of leaded windows.
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.
