Schloß Eggenberg is all but traditional - even though it dates from the 17th century. The first hints of its commissioner’s eclectic taste are the many peacocks that greet you in the palace gardens. But it is only on a tour of the state rooms that Schloß Eggenberg will reveal its strange secret to you: the palace’s entire layout is centered around the Gregorian calendar. It has exactly 365 windows, 31 rooms on each floor, 24 state rooms with 52 doors and 4 corner towers, which allude to the then brand-new measures of days, hours, months, weeks and seasons. Even the castle’s ornate Planetensaal, or Planet Hall, is part of this grand concept. Schloß Eggenberg will surprise any visitor with its hidden features, but also amaze them with what is clearly visible.
