It's a steep climb up here, no matter which direction you come from. Unfortunately, the gate is still locked early in the morning, and you can't get in.

It is difficult to call it a castle, it is simply a shaded 360° panoramic terrace. In addition to this, it allows a small tour of the lower part where you can see the gardens, a fountain and the tower. Public toilets are available. A nice stop between the hills and the upper city...
