I recommend buying the castle tour (9€) because that is the only way to get to the tower. In one of the towers is a medieval WC and it is very cool. In the autumn season the last tour starts at 15:00.
Get to the castle! If you enjoy any kind of castle, this is the place to visit. During the Opera festivals the courtyard isn’t anything to see, but otherwise a magnificent place.
Экскурсия на русском языке - просто чудо! Количество экскурсантов не имеет значения и это обрадовало! Очень интересно рассказывают, не хотелось уходить! И город, и крепость рекомендую к посещению!
