This one of the few surviving authentic 18th-century court theatres in
Europe, and the only example of its kind in Poland. The interior is
constructed of wood, which provides superb acoustics. In places it has
been covered with marbleized polychromes.
The two-storey auditorium can accommodate 200 spectators. On the
ground floor level, simple benches are set on risers, while the first
floor contains nine theatre boxes, three on each side of the auditorium.
The central one, located directly opposite the stage, was reserved for
the King. Set between the boxes are eight female figures made of stucco,
holding gilded wooden candlesticks. The figures were designed by the
royal sculptor Andre Le Brun, and executed by his assistants working at
the royal Sculpture Studio - Giacomo Monaldi and Gioacchino Staggi.
Above the boxes, the illusion has been created of yet another level,
with illusionistically painted semi-circular arcades decorated with
stucco work, filled with an 18th-century court audience. The creator of
this decoration, as well as the remaining illusionistically-painted
architecture, was the talented royal artist Jan Bogumił Plersch.
