Skopje - walk along the Kale fortress walls
There has been a fortress of some kind at Skopje for over 1,400 years. Some of the ancient walls are still partially standing, thanks to renovations carried out in the 18th and 19th centuries. A walk along the walls, gives you a great view of the city, and a little piece of history. Extensive excavations are happening all around and near the fortress, from which more details of the ancient city and its inhabitants are found all the time.
