In 1821 the monastery was restored again on the old foundations.
The one-apse, one-nave Church of Holy Ascension was constructed, with dimensions of 7 by 14 meters.

Three large domes of the old cylindrical building, built by the master Tsvyatko Todorov from the village of Zhablyano, near the town of Radomir, are still intact today.
They were quite unusual for the Bulgarian architecture from that period.

From another inscription below, we learn that in 1869 the Samokov painter Nikola Ivanov Obrazopisov with his assistants Hristaki Zahariev Zografsky and Dimitar Hristov Dupnichanin repainted the church and three domes.
The frescoes, which are preserved today in relatively good condition, attract pilgrims and visitors with their rich colours and craftsmanship.

Another interesting fact connected with mural paintings is that in no other temple in Sofia there were depicted so many Bulgarian saints and historical figures.
Along with biblical scenes, Nikola Obrazopisov painted images of Saints Cyril and Methodius, Michael Voin, Bishop Marko, John of Rila, Euthymius of Tarnovo, Onufari of Gabrovo, Constantine of Sofia and the revered by the Bulgarians St. Petka and St. Nedelya.
Also interesting are the realistic donor portraits of abbot Kiryak from 1868 and the icon of St. Jovan Vladimir, a Serbian prince married to Kosara, a relative of the Bulgarian emperor Samuel (r. 997–1014).

According to the legends of the local people, the St. Spas Monastery has been a centre of the national liberation movement.
Vasil Levski stayed there.
After the Liberation in 1878 a school with several large rooms and a separate room for the teacher was constructed next to the monastery.
Until 1900 the monastery was male and then was converted into a female abode.
