The Gorno Ezerovo Monastery of St. Mary is located between the neighborhoods Meden Rudnik and Upper Ezerovo in Bourgas near the village of Cherni Vrah.
According to the legend the building of the Monastery of St. Mary goes back to the 12 century.
The monastery was built near a former Thracian sanctuary of healing springs, each of which has a different chemical composition and medicinal properties.
Later a guesthouse was built close to the monastery to shelter the guests, who had arrived here to be treated. In its present form the Monastery of St. Mary consists of two churches, 40 chapels and houses and the whole complex is maintained solely by mother Seraphima.
