The Blešno castle ruins are located on the 520 m high Blešenský vrch. Today, only a few ditches, ramparts and barely recognizable remains of buildings remain. Unfortunately, no documents on the history of the castle have been preserved. It is assumed that it dates back to the Hussite period and consisted mainly of wood.
However, from the top of the castle there is a wonderful view of the surrounding Bohemian Central Mountains and to the south far out into the plain. A visit can be combined with the neighbouring Oltářík.
