Holy Trinity Church (Sveta Troitsa) is the centrepiece of Varosha and the largest church in the region. The freestanding bell tower, added in 1850, was for decades the tallest building in Bansko and is still the landmark you navigate by. Inside, the interior is generously decorated with frescoes and iconostasis work by masters of the Bansko Icon Painting School.
The church and the cobbled square in front of it are free to enter and open during daylight hours. Stop in for ten minutes for the icons and the unusual sunken floor. The square hosts the main Jazz Festival stage in August.
