The upper castle consisted of a palace, a square tower and stone walls. This castle core is accessible through the back of the cannon bastion. It can be accessed from the western barrier, also secured by a cannon bastion. The castle was fortified in the first third of the 15th century. Further construction work was carried out at the turn of the 15th and 16th centuries, when they built several cannon bastions with gunfire. The next phase was the completion of fortifications in the mid-16th century. At the beginning of the 17th century, they reinforced the wall above the entrance to the upper castle and surrounded the castle with artillery bastions.The medieval castle has been preserved mainly the masonry palace and neck tower and the interior of the building little remains of Renaissance vaults. Stone walls are broken by irregular window openings, now without borders. From the original architectural details, a Gothic round window with a richly designed profiled lining has been preserved. Entrance semicircular Renaissance gate leads to the first courtyard.Nowadays, the castle has been under reconstruction since 2011, the progress of the reconstruction work carried out by the municipality of Jasenov is noticeable. The Association for the Rescue of Jasenov Castle also cooperates with the municipality. Surroundings of the castle is cleaned from trees and trees and open to visitors.

Some sources attribute the founding of Jasenov Castle to the Gutkeled lords, to whom the documents of the Raškai and Butykai families refer. However, other sources state that the oldest part of Jasenov Castle was probably built by Master Peter, son of Petr Petény, at the turn of the 13th and 14th centuries. However, Peter then rebelled against the monarch and King Karol Róbert took away his property and donated it with the castle to the nobleman Filip Drugeth in 1317. In 1328, a year after Philip's death, the property was inherited by his nephew Viliam Drugeth. The Drugeths built a manor in Humenne at the end of the 14th century and began to use the surname de Hommonai.

When the Hungarian-Polish disputes subsided at the end of the 15th century, the threat of Ottoman aggression appeared, as well as political unrest after the extinction of the Jagiellonians. Gabriel Drugeth took advantage of this situation and started minting counterfeit coins at Jasenov Castle. The Drugeth line died out in 1610 after Gabriel, and the castle became the property of the second branch of the family. Later, the castle was acquired by Alžbeta Báthora's grandson - Ján Drugeth, who was appointed chief captain in 1635. In the anti-Habsburg uprising, Ján remained loyal to the monarch, and therefore in 1644 the insurgents of Juraj I. Rákóczi surrounded his castles and severely damaged Jasenov. The Drugeth family did not restore the destroyed castle, as at that time they were already completing the reconstruction of the Renaissance manor house in Humenné.

The castle belonged to the Csáky family in the 18th century and to the Andrássy family in the 19th century. At the end of the 19th to the beginning of the 20th century, it was partially preserved.

The rumor says

When Štefan Bocskaya's treasures were transported through Zemplín, Valentín Drugeth robbed the procession, seized 17 chariots and hid the loot, which also included two royal crowns, on Jasenov.

Castle lord monk

At the place below the castle, where the water from the stream once returned the beggar's gaze, a chapel grew up, where crowds of pious people gathered on Sundays. Only the lord of the castle, Drugeth, did not keep this day holy. One day, however, returning from the hunt, he fell from his horse by the chapel and broke his arm. In anger, he ordered the chapel to be demolished. However, his terrible pain only disappeared when he humbly returned to this miraculous place, where, out of gratitude for his healing, he had a monastery built and entered it himself as a pious monk.

The ruin is freely accessible. The castle is undergoing reconstruction.
