It is presumed that it was once used as a woad storehouse, and the two holes in the wall next to the entrance indicate that it was used as a brewery. Since 1988, after extensive restoration, this building has been used as a wedding house and registry office. The magnificent portal and parts of the half-timbering have been preserved in reconstructions.
