After the abrogation of feudal duties in 1812 the village became a selfgoverning municipality.

The oldest building of the small town is the Baronial rural farm, that since the ancient periods has been the owner's residence and later it became a firm and a structure of control for the territory. Adjacent to it there is the Cathedral Church consecrated to St. Anna and since 1809 it has been opened to faith.
