There's an interesting website called sacredsites.com
My girlfriend and I spent a month in France and Italy and based our whole trip around that website. Some of the places we went to, it just said, "cave where Saint Benedict sat in silence". But, we were game, so, we rocked on up there. On the way, we were thinking, 'what if we have to hike 2 miles into this place'. It ended up being this really cool castle with super old art work. It was full of the monks of St. Benedito, and one of the monks spoke English. We ended up getting this really nice tour of the castle, the cave, and the artwork with a huge history lesson. It was awesome!
Have fun!
Love,
