It stands on a hill featuring rare plants, and has been declared a national nature reserve for this reason.

The castle was a residence and later the prison of the Countess and alleged serial killer Elizabeth Báthory.

[1] Čachtice was built in the mid-13th century by Kazimir from the Hont-Pázmány gens as a sentry on the road to Moravia.

Later, it belonged to Matthew Csák, the Stibor family, and then to Elizabeth Báthory.

Originally, Čachtice was a Romanesque castle with an interesting horseshoe-shaped residence tower.
