Initially I thought the entrance fee (€10 in August 2023) was a bit steep, especially after a strange incident with a ticket lady. She dragged me (and another family) to pay at a self service machine and insisted on entering all the details herself to evidently stop us claiming to be a child and paying less...
Anyway, once inside I wasn't overly amazed at the beauty vs cost of entry balance. After looking around more and going to the roof I take it back and would recommend it highly.
