Hisarya Fortress, also known as Lovech Fortress, crowns Hisarya Hill overlooking the city of Lovech and holds profound significance in Bulgarian medieval history. Dating to the 9th–10th century, the fortress achieved its greatest importance during the 13th–14th centuries when it served as an administrative, spiritual, and commercial hub and residence of Despot Ivan Alexander, Bulgaria's tsar beginning in 1331. The fortress witnessed a pivotal moment in 1187 when the peace treaty declaring Bulgarian independence from the Byzantine Empire was signed within its walls, marking the birth of the Second Bulgarian Empire. Extensively excavated, the site has yielded coins, pottery, jewelry, and remains of seven churches representing three architectural styles, with the oldest church on the hilltop dating from the 5th century. Remarkably resilient, it withstood Ottoman invasions longer than most Bulgarian strongholds, finally falling in 1446, and today offers commanding views of the city below.
