Mogilitsa is famous for Agushevi konatsi (Агушеви конаци), the 19th-century winter estate of a rich Ottoman feudal lord, Agush Agha (title) who belongend to the Pomaks, and his three sons.
Built in 1825-1872 by local Bulgarian masters, the castle-like complex consists of three buildings with a separate yard surrounded by a common wall with a richly-decorated tower in the southeastern corner.
Northwest of the village lie the ruins of an old fortress, possibly from Thracian times.
Three kilometres to the east of Mogilitsa is Uhlovitsa, one of the twenty caves in the vicinity of the village, which features water cascades and small underground lakes.
