Castle Krašov, Gothic castle ruins in Bohy, Czech Republic.

Castle Krašov stands on a rocky promontory above the confluence of the Brodeslavský stream and the Berounka at 310 m, near Bohy. Its L-shaped footprint has a tall jagged fragment on the left, a long red-brown metal roof over the centre and right, three small and two taller arched windows, and an open archway at the base.

Founded in 1232 by Jetřích of the Hroznatovec family, the castle received its Gothic shape in the 13th century. Renaissance modifications in the 16th century added new elements to its appearance.

The castle name comes from the village below, and the lords of Krašov, a branch of the Hroznatovci clan, took their title from it. In the 18th century the site served as a summer residence for the monks of Plasy Monastery, until the monastery's dissolution in 1785 left it unused.

The ruin stands on a rocky promontory at 310 m above sea level, above where the Brodeslavský stream meets the Berounka, about 1.2 km north of the Krašov settlement near Bohy. It is reached on foot; the site has been a protected cultural monument since 1964.

The castle was founded around 1232, but the first written record of the Krašov family dates from 1284, when Sezema of Krašov is mentioned. The site was protected by a bastion on a plateau about 50 metres above the castle, which stood within its field of fire.
