There is a very quaint cute cloister, but unfortunately there were quite a few visitors crowding the whole place, given that there's a flower festival and everyone was just so into flowers during that time. As you can see in my photos above, there's plenty of flowers on display in the cloister. This cloister is actually a very good specimen of Catalan Romanesque architecture.
There is an austere skeleton of a church that now serves as an exhibition space. There were some archaeological displays, but for the most part, people were interested in the flowers. I do recommend checking this out, but perhaps it's better if there's no massive festival going on.
