The ticket costs 11,5 euro. I find it too expensive, considering the fact that the place is not big. The butterfly house is nice, but I saw better in the past.
The ticket costs 6 euro. You can visit this Palace only with a guided tour, that takes 1 hour. There are 34 rooms to visit, so the tour is at a really fast pace. It’s really a pity that there is no possibility to visit the palace with an audioguide anymore, but financially it was not worth it, as the guide said.
