Porta coeli Convent, Cistercian monastery in Předklášteří, Czech Republic

Porta coeli Convent is a Cistercian monastery in Předklášteří, its pale stone ranges with reddish-brown tiled roofs set below a wooded hill. The convent church, consecrated before 1239, is a three-nave basilica with a transept and five-sided chapels opening into it. The early Gothic complex, built in the Burgundian style of the Cistercians, survives largely intact.

Constance of Hungary, widow of Přemysl Otakar I, founded the Cistercian convent at Tišnov in 1233, after the site was moved from Prague following the king's death in 1230. The convent church of the Assumption was consecrated in 1239. Hussite wars destroyed the complex, and it was refounded under Abbess Elizabeth IV in the 1440s.

The western entrance displays French cathedral design principles, featuring sculptures of apostles and lions as decorative elements on its facade. These features show how western European building styles influenced the religious architecture of this region.

The convent church of the Assumption of the Virgin Mary serves as the parish church of Předklášteří. The former convent buildings, rebuilt after 1625, stand around the church; the complex lies 25 km northwest of Brno, below a wooded hill.

An asteroid numbered 3276 carries the name of this Czech monastery as international recognition. This unusual honor connects the medieval religious site with modern astronomy.
