A sprawling set of ruins just off the highway near the town of Gradsko, Stobi is the largest archaeological site in Macedonia. Thanks to its strategic location at the confluence of the rivers Crna and Vardar, Stobi was an important city for both the Paeonian Kingdom and the Romans, until being abandoned after a major earthquake in 518 AD.
Halfway up Ohrid’s biggest hill, between the Church of Sv Jovan and Tsar Samoil’s Fortress, is the archaeological site of Plaošnik. With the arrival of St. Clement in 893 AD, and the subsequent establishment of his monastery, this location became the center of Slavic learning. Today, the Church of St. Clement has been rebuilt and much of the site has been excavated, revealing long-concealed Byzantine mosaics.
