It is a hilltop castle located on a fairly steep, roughly cone-shaped hill with a limestone bedrock, in an altitude of approximately 392 m (1286.08 ft) above sea level.

The Drugeth family retained ownership of the castle until its demise in 1644, when it was destroyed by one of the armies of George I. Rákoczi, during one of the period's anti-Habsburg uprisings.

All conservation works on Jasenov Castle were halted by World War I, due to economic reasons and the fact that the town of Humenné became part of the front line in late autumn 1914 and suffered major damage.

[6][7][8] A concerted and systematic effort at new archaeological research and ruin conservation works on the castle was launched only recently, at the start of the 2010s.

The administration, research and conservation works of the association are conducted in official cooperation with the Jasenov municipality and the regional branch of the Monuments Board of the Slovak Republic.
