St. Nicholas' Church

The monastery church of the former Franciscan monastery of Cottbus is the oldest preserved sacred building in the city. It was built in its present form in the 15th century in the Gothic style. The last remnant of the monastery buildings was not demolished until 1852. The monastery church is also called the "Wendish church", as it was the parish church for the Wendish (Sorbian) population.

The Neuzelle Abbey was a Cistercian monastery founded in the 13th century. Between 1655 and 1658, Abbot Bernardus had the reconstructed buildings decorated with frescoes and stuccoes by Italian artists. Secularized by the Prussian government in 1817, the monastery's domains passed to the state-run Abbey of Neuzelle, which existed until its nationalization in 1955. In 1996, the foundation of Neuzelle Abbey was re-established as a foundation under public law of the Land of Brandenburg. The church of the Monastery of the Assumption of St. Mary is a pilgrimage church and parish church.

Dobrilugk Monastery was a Cistercian abbey founded on 1 May 1165, the day of King Sigismund of Burgundy, and was therefore dedicated to Saints Sigismund and Henry. It existed until its dissolution during the Reformation. Although the son of Emperor Ferdinand I was able to regain dominion of the monastery during the Schmalkalde War (1546-1547) and reintegrate it into Lower Lusatia, the Catholic ruler did not allow other monks to enter the monastery. Today's Doberlug Castle was built on its grounds after the end of clerical life in the middle of the 17th century.
