The monastery is a little old gem embedded in a brand new city, the oldest building in USA for sure.
The garden is really nice, the building is beautiful - maybe because was made in europe centuries ago - and walking in the cloisters you can almost feel in medieval Spain. Frankly i could live without christmas decorations in the inner garden close to the well, but the little church (they actually hold services and weddings there) was fine and the walk was relaxing and peaceful. You should take a look at the "signatures" of the stonemasons.
Besides this beauty, we were disappointed when we got there around 11am and we were told to come back at 1pm because the monastery was closed (despite the sign saying that opening time was 10am).
Tickets cost 8$ (4$ for students).
Good place if you want to admire european beauty in the middle of Miami. Anyway i hope no one else decides to bring something so ancient outside of europe.
