Entrance is $15 but it is free on the first Thursday of every month. You have to get reservations to get into the cafe and tea room and you better not be late because you will loose your place if you do. The museum was not much and could be skipped. The libraries collection is rather extensive. They have beautiful gardens behind the library. You can do your own tour or have a guided tour which you do not pay extra for. I thought the tour was fun because the guide was hilarious. I cant guarantee you will get the same one because she is a volunteer. You can easily spend a whole day here so plan ahead.
