Kościół pw. św. Kazimierza, Warszawa

At New Town Market Square, you face St. Casimir Church, a Roman Catholic sanctuary dedicated to Saint Casimir. It began as Adam Kotowski’s residence, until Queen Marie Casimire acquired it in sixteen eighty-eight and converted the property for Benedictine nuns devoted to perpetual adoration.

Tylman van Gameren devised the church-and-convent complex, giving this former home a Baroque character: a dramatic, theatrical manner made for ceremony and grandeur. Notice the dome crowning the compact mass. Beneath it, the building follows a Greek-cross scheme, with arms of equal length meeting beneath the dome.

The church opened in sixteen ninety-two, yet much of what you see recalls a painful rebirth. During the Warsaw Uprising, the nuns turned church spaces and cellars into a hospital and shelter, then set aside their enclosure rules to care for wounded insurgents. A German bombing raid on the thirty-first of August nineteen forty-four killed four priests, thirty-five nuns, and more than a thousand civilians sheltering in the crypt.

The church and cloister were ruined. Reconstruction followed after the war, though the former Kotowski Palace did not return. Inside, a surviving treasure is the reconstructed memorial to Maria Karolina Sobieska de Bouillon, carved in contrasting marble.
