This is a wonderful ancient abbey in the mountains north of Milan. It is free to visit, but check the opening hours, and be aware that the only way to reach the abbey is by steep rocky mountain path. The easiest path goes from the town called Civate. Also be aware that Google Maps does not give you the right directions (probably because it does not take into accounnt mountain paths). We made a mistake of going all up to the mountain and then descending back to the abbey. In any case, it is a moderately intense hike, so be prepared (wear hiking boots, get some water). You will be rewarded by the masterpiece of medieval Lombardian architecture as well as a wonderful view on the lake. Inside, there are ancient frescoes and some carving. Friendly staff does not speak much English, but ask for an English audioguide.
