The Church of the Assumption of the Holy Virgin stands in a stone-walled courtyard at the centre of the Varosha old quarter. The current building dates from 1844 — constructed during the Bulgarian National Revival period, when the Ottoman authorities allowed Christian communities greater latitude to build and restore churches. The exterior is modest; the interior has a richly carved wooden iconostasis and a collection of 19th-century icons.
The surrounding courtyard with its old mulberry trees is one of the quietest and most pleasant spots in Blagoevgrad. The Atlas Obscura entry on the nearby Gotse Delchev Temple refers to another significant religious site in town — a synagogue that survived because the local community actively resisted deportation orders during the Second World War; the building still stands on Bulair Street.
