Nikopol Fortress, Medieval fortress overlooking the Danube River in Nikopol, Bulgaria

Nikopol Fortress is the ruin of a medieval fortification that stands on a steep hill between the Danube and Osam rivers. It consists of stone walls and defensive structures that remain partially preserved today.

The fortress was built as the last refuge of Bulgarian Tsar Ivan Shishman and fell to Ottoman forces in 1395, marking the end of the Second Bulgarian Empire. Russian troops later destroyed the site completely in 1810.

The best-preserved structure is the so-called Shishmanova Vrata (Shishman's Gate), which stands on the site today. Despite its name, it was not built under Tsar Ivan Shishman but at the beginning of the 19th century. The fortress is also known as Tsar Ivan Shishman's Fortress.

The path to the fortress climbs steeply from Nikopol town center, and sturdy shoes are recommended because of the uneven terrain. Guided tours are available through the local tourism office and provide helpful context about what you see.

The gate known as Shishmanova Vrata, the best-preserved part of the fortress, does not date from the reign of Ivan Shishman at all: it was built in the early 19th century, centuries after the tsar's death in 1395.
