This is a very beautiful church just off of the Plaza de Armas opposite of the Cathedral. The carving of the sillar around the outside of this church is beautiful. The inside of this church is still the white sillar and is beautiful.
To the left of the alter there is an entrance to a small chapel where a couple of tour guides claimed it looked like the Sistine Chapel. I hope it does not look like the Sistine Chapel because it really was not worth the dollar or so that it cost me to get back there. It is basically a coupula that is painted in jungle motifs.
Also visit the old cloisters of the church which are located just to the left of the church entrance. Here you can find all of the touristy type shops located in the beautiful cloisters of the church including alpaca woolen goods.
