The Etropole Monastery of the Holy Trinity (Bulgarian: Етрополски манастир „Света Троица”, Etropolski manastir „Sveta Troitsa”), also known as Varovitets (Варовитец), is a Bulgarian Orthodox monastery near the town of Etropole in west-central Bulgaria. The monastery was founded in the 12th or 13th century, its heyday being from the 16th to the 18th century when, thanks to its prolific scriptoria, it was the dominant literary centre of Ottoman-ruled northern Bulgaria. In its present form, the monastery includes a large mid-19th-century church and two chapels.
