Ronov Castle, Medieval castle ruins in Ronov nad Sázavou, Czech Republic.

Ronov Castle is a ruin of a castle in the Vysočina Region, east of Ronov nad Sázavou near Přibyslav in the Havlíčkův Brod District. It stands on a private plot used as a game enclosure and is freely accessible to visitors. The first written mention dates from 1329, when Smil of Ronov, a descendant of the Ronovci family, was named after it.

Ronov was first documented in 1329, when Smil of Ronov issued a charter; it was probably founded by the lords of Lichtenburk as a guard castle on the trade route between Německý Brod and Žďár nad Sázavou. Hussites besieged and damaged it on 7 October 1424, in the campaign during which Jan Žižka died four days later. It was last called habitable in 1516 and described as deserted in 1538.

The castle's name comes from the Ronovci coat of arms, which bore a bundle of rods called die Ronne in German. A chapel of the Assumption of the Virgin Mary was founded at the castle in 1381, and the village of Čachotín was assigned to support its chaplain. The ruin now stands on private land used as a game enclosure.

The site is freely accessible and located on a hilltop that requires a walk uphill, so sturdy footwear is recommended. Keep in mind that you are visiting ruins, so paths and structures can be uneven and potentially slippery, especially after rain.
