This place is really great, you have to visit it at least once as it makes us a visit to the past. It is very interesting to see the construction techniques of the Middle Ages used, especially since the staff are very friendly and open to discussion when they are stationed. I have been there three times in an interval of fifteen years and it is something to see for myself the progress of the work! Special mention to the vaults of the tower and the chapel, magnificent!
Beware of the crowds, which can be very high in summer: wait at the ticket offices! Fortunately the parking lot is large
