The castle in Krupe is an excellent example of a late-Renaissance, fortified residence. It was built on the initiative of Paweł Orzechowski at the end of the 16th century and enlarged in the years 1604-1608. It was destroyed during the attacks of the Cossack and the Swedish armies as well as by the fires in the mid-17th century. Although it was partially re-built, it fell into decay since the mid-18th century.

Some parts of the castle stood the test of time, these are: the walls of the castle are surmounted with attic with pinnacle apices and volutes, the construction fragments of the towers, and the traces of moats. The building was decorated with sgraffii with motifs of balustrades and twigs, which have partially remained above and under the window openings. In the southern part of the castle, there was an arcaded gallery. The moat used to separate the castle from the homesteads lying at its foot. Moreover, anyone willing to enter the castle had to cross the drawbridge. The homesteads lying at the foot of the castle were surrounded with ramparts. The restoration works were conducted in the 60s of the 20th century. The ruins were then secured and partially renovated.
