In 1529, during his journey through the northern lands, Vasily IV Ivanovich and Elena Glinskaya visited the monastery. Soon, in 1536, the construction of the Assumption Cathedral began, as evidenced by the inscription on the church's foundation cross. In 1538, the Tatars burned the monastery, leaving only stone structures. This indicates that the construction of the Assumption complex was nearly completed and the monastery was given special significance, as by 1539 the construction of the refectory complex was practically finished, which would have been impossible without help from the center after the looting. In 1545, Ivan the Terrible visited the monastery, and at his command, in 1546, a church was built over the canopy of St. Paul of Obnorsk.

Thus, in the 16th century, the Pavlo-Obnorsk monastery became a significant center with a complex of stone buildings. In addition to three churches, by the end of the 16th century, a building may have been constructed south of the Assumption Cathedral.

According to the scribal books of 1628-1630, the monastery looked as follows: "The Pavlov Monastery on the river Nurma, with the Church of the Life-Giving Trinity with the chapel of Paul of Obnorsk, another church of the Assumption of the Virgin Mary with a refectory, and a third church of St. Sergius of Radonezh, all three stone. The monastery also had the abbot's cell, a treasury cell, and 20 brotherly cells."

In Suvorov's book, written between 1861-1866, the monastery is described as "almost a regular quadrilateral, with a circumference of 277 fathoms." From 1881 to 1887, a 20-fathom bell tower was built on the site of the Assumption Church near the refectory. The monastery's documents record the construction of the bell tower starting in 1880, beginning with the laying of the foundation. In 1884, the Assumption Church is mentioned on the second floor, although work on the bell tower continued, and the masonry reached 7 fathoms. On September 21, 1886, the Assumption Church was consecrated, while the bell tower continued to be built over the altar. The construction was completed in 1887. In 1910, a large dome covered with white aluminum was installed on the bell tower, topped with a gilded cross, and the Assumption Church itself was renovated.

In 1922, the monastery was closed, and the buildings were transferred to the Vologda regional special regime school, then in 1947 to an orphanage. From 1953 to 1986, the monastery buildings housed a school for children with weakened lungs. From 1986, the buildings belonged to the Gryazovets boarding school but were not used.

The Assumption complex, including extensions from 1536 to 1886, is of the greatest scientific interest. It includes the refectory from 1536-1539, which has been repeatedly rebuilt but has preserved the original finishes in the attic along the eastern, northern, and western walls, as well as the piers and remnants of vaults in the wall masonry. The abbot's quarters adjoin the refectory from the west. The two lower floors date back to the 16th century, while the third was added in the mid-19th century. The bell tower, specifically the two lower tiers that remain on the site of the Assumption refectory church, are in good condition. The upper tiers, including the ringing tier, were dismantled in the early 1950s, and the bricks were used for agricultural buildings.
