Palčava Šiša is a Čop family house from 1856. It is a cultural monument located on the Croatian-Slovenian border, in the centre of Plešce. The house showcases the life of a rich farm from the mid-19th century, as well as the life and culture of the people living in the Čabranka valley.

The estate preserved the old shop with original equipment, the vaulted ceiling of the ground floor with a presentation of the inn, and the old office on the floor above, as well as the abundantly furnished and decorated salon from the 1880s and the bedroom. The ethnographic collection, attic and vaulted ceilings of the former wine wholesale can also be toured. The house also includes an outbuilding, the only such fully stone building in the valley.
