The ruins of the former Markaz castle at the end of Vár crag lie about 2 km way from Markaz. It is assumed that the Kompolti family that belonged to the Aba genus had it built in the 1270-1280's. The castle did not have significance from a military point of view as it was mainly used for recreation and hunting by the owners. The palace was constructed in the tiny and narrow castle with a tiny yard. On the southeast side of the rectangular castle the 6-metre wall still exists. The castle is believed to have been demolished during the Turkish occupation. There is a spectacular view from the castle to the north to the castle valley and Abasár why it is worth climbing.
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.
