Though there is not much to see inside this mediaeval church apart from bare stone walls and a few fragments of frescoes, it is worth a mention as a landmark and cult building due to its place in Bulgarian history. The church's construction was financed by artistocratic brothers Assen and Peter who, at its consecration in 1185, declared independence from the Byzantine empire (a big thing after nearly two centuries of suppression) and subsequently led a war to secure Bulgaria's liberty, which resulted in them being crowned as Tsars. The church is located in the Assenova Mahala down by the Yantra river below Tsarevets.
