Lydstep Palace is a ruinous medieval hall house. Believed to have been built in the late 14th century or 15th century, the building was constructed from limestone and built in two levels, the upper floor containing a hall and the lower floor consisting of several barrel vaulted rooms, likely cellars. The two floors were not connected internally, only by external stone stairs. Speculation as to the purpose of the house varies, some sources attribute the building as a court of the Manor of Manorbier and Penally, but it has also been referred to as a hunting lodge of the Bishop Gower of St. Davids.
The house was traditionally known as the Place of Arms, and it is speculated that this became mutated to the Palace of Arms, leading to its current name of the Palace. The building is also referred to as The Old Palace.
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.
