31a Krasińskiego Street. The St. Jan Kanty church.
Before the war the building of the Resurrection Sisters convent was started to be built at the corner of Stołeczna (presently it's Popiełuszki street) and Krasińskiego street. Till the war only a part of the building was finished. During the first three weeks of the Uprising the convent played a role of an uprising hospital. It was then removed to Krechowicka street.
In the convent which was later called "The Fortress of the Resurrection Sisters", the insurgents of the Unit "Żyrafa" remained, fighting fiercely with Germans. The building was in 80% damaged.
After the war the nuns were able to rebuild the façade at the site of Stołeczna street and party at the site of Krasińskiego street. The missing part was replaced in the 80s with the part of the St. Jan Kanty church.
In the year 1958, while tidying the ruins at the site of Krasińskiego street, the corpses of four insurgents were found. The solemn Holy Mass in their intention was celebrated by Fr. Zygmunt Trószyński, the chaplain of the Żoliborz insurgents, a.k.a. "Alkazar".

On the wall inside the church one can find a plaque in memory of the fallen soldiers of the 9th Combat Sabotage Company "Żniwiarz".
On the outer wall of the convent, next to the church there is a plaque with the information of the insurgent hospital and "The Fortress of the Resurrection Sisters".
