Tsarevets is the dominant sight in Veliko Turnovo and one of the best-preserved medieval fortresses in Bulgaria. It sits on a rocky hill enclosed on three sides by a dramatic horseshoe bend in the Yantra River, connected to the surrounding city only by a narrow neck of land and a reconstructed stone bridge. The hilltop was the political and spiritual centre of the Second Bulgarian Empire (1185–1396): the royal palace, the Patriarchal Cathedral, dozens of churches, and a large residential complex all stood within the walls.
Today the ruins cover the entire hilltop. The Patriarchal Cathedral has been partially reconstructed, its interior decorated with controversial modern frescoes by the artist Theophane. Baldwin's Tower, where the captured Latin Emperor Baldwin I was held prisoner in 1205, stands at the hill's southern tip. The views from the walls over the Yantra gorge and the surrounding city — with its old houses cascading down the slopes — are exceptional. In summer, a sound-and-light show projects onto the fortress walls in the evenings: not subtle, but genuinely dramatic. Entry fee applies.
