The church from Mănăstireni is considered by specialists as the most valuable of the fortified churches that can be found in Ţara Călatei. Built in the 13th century, it is a Romanesque style church hall, it is supposed to have been originally a monastery of one of the noble families in the area. The initial construction underwent several interventions, so that today we find both elements of the Romanesque style and elements of the Gothic or Renaissance style. The furniture, pulpit and coffered ceiling date from the 18th and 19th centuries.
The enclosure wall dates from 1734, it represents the restoration and consolidation of some older fortifications that protected the church. The façade of the western tower contains elements that give the special value of this monument: a bas-relief with a virgin breastfeeding two snakes -a unique architectural element in Transylvania- two funerary lions from the Roman Empire, a bas-relief with St. Archangel Michael killing the dragon and a solar clock. The most imposing tower is the northern one, with a high helmet made entirely of wood and covered with shingles, with four smaller corner towers – which is a specific element of the Călata area. From the Reformation era until now, this building has remained the church of the Reformed Calvinist parish in Mănăstireni.
