a very nice museum full of treasures divided into 3 parts: the first is a temporary exhibition of the book-making in the monastery, specifically songbooks, the second is a treasury with beautiful relics, in the last there are statues and paintings, the museum is dedicated to Christianity, it is very informative, educational, clean, toilets, coat hangers available, English speaking  staff, only minimum entrance fee, definitely worth seeing
