In the interior there are several interesting apartments; the chief of these is the ample council chamber with its fine tapestries, where an important wine sale is held annually.
The inner walls are often hung with hand-woven tapestries, which harmonize well with the smokeblackened rafters, the primitive loom and the huge Dutch stove characteristic of a prosperous Rumanian farm.
Medieval tapestries, with ecclesiastical vestments, ornaments and some fine pieces of early woodwork, are also preserved in Bucharest museum.
The carved wooden doors of both the north and the south portals are masterpieces respectively of Gothic and Renaissance workmanship. The church possesses an elaborate astronomical clock (1866) and tapestries of the 15th and 17th centuries; but its chief artistic treasures are stained glass windows of the 13th, 14th and 16th centuries, the most beautiful of them from the hand of the Renaissance artist, Engrand Le Prince, a native of Beauvais.
The Museo Civic°, formed in 1903, contains collections of antiquities (though many of the Roman antiquities of Piacenza have passed to the museum of Parma), some good Flemish tapestries and a few pictures.
