Hiking the old city walls of Kotor in Montenegro is definitely only for the physically fit. We preferred to just look at them at night! The first night after we arrived, we saw the walls lit up and didn't know what they were. It's hard to imagine the physical labor that went into building them. Their construction started in the 9th century and in the 15th century they finally formed a full loop up into the hillside, 4.5 km long. We went there to climb a portion of them one day, as we didn't have time for the full climb, but we got up high enough to have a beautiful panorama of Kotor and the bay. The first stop for most hikers is the Church of Our Lady of Remedy, where we decided that was far enough! The church was built in 1518 by survivors of the 14th century plague and became a site for people to make pilgrimages to. Crazy beautiful, especially at night.
