Vertical sundial on the west side of the south facade of the north wing. It is dated to the 18th century. The central field is framed by a multifold red ribbon. On the lower side is a dial with black painted Roman numerals (IX, X, XI, XII, I, II, III, IIII), and on the upper side is a Latin inscription from which only part of the word is recognizable, ‘singVL’, apparently a chronogram.
