Monastic foundations
On returning from Athos, Joachim and three disciples settled in the gorges of the Rusenski Lom river near the village of Krasen, carving a small rock church into the cliffs. His reputation reached Emperor Ivan Asen II, who visited him and formed a close spiritual bond with him, donating substantial gold for the construction of the Church of Archangel Michael — later known as the 'Buried Church' — which became the center of an expanding monastery.
The community he founded in the 1220s near the village of Ivanovo grew into the Rock-hewn Churches of Ivanovo, a complex that at its peak contained roughly forty churches and some three hundred additional structures perched on rocky banks above the Rusenski Lom. Patronized by the rulers of the Second Bulgarian Empire, it became a center of hesychasm in the fourteenth century and is renowned for its thirteenth- and fourteenth-century frescoes, considered outstanding examples of medieval Bulgarian and Palaeologan art. The site was inscribed on the UNESCO World Heritage List in 1979.
