This church and convent building has a very impressive facade. The convent has been converted into a 5 star hotel by Parador. Only hotel customers can enter that side of the building that was the convent.
However, the church on the right hand side of the building can be visited by public and it also houses a collection of artwork that is on display. The cloister is open to public also.
This is also a must visit place while you are in Leon.
