The walled medieval town of Cabrejas del Pinar was the leader of its Community of Burgs and Land and there are some traces left of the walled enclosure and fortress that protected the locals. The castle was built in stone on top of a high rock possibly between the 13th and 14th century.
Some of the walls, doors and the keep are still visible which helps understand how the fortress’ layout once was. The quadrangular keep was built in stone masonry and reinforced with ashlar on the corners. On some of the higher floors, you can still see wood fixed in holes that supported the wooden floors on each of the four stories. The access door can still be seen and is located on the south-east wall defended by watchtowers and an opening.
On the eastern part of the walled enclosure, there is still a circular watchtower placed there possibly in the 10th century in order to have better visual control over the Caliphate’s territories.

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.
