On the southern side of the Assumption Cathedral is the Archiepiscopal Courtyard, one of the oldest buildings in the Astrakhan Kremlin. Initially, there were wooden chambers built in 1617, which were replaced with stone in the 1680s. The Archiepiscopal House included a chapel, living quarters, and archiepiscopal chambers shaped like a rectangle, extending from east to west. The facade of the building features tiles depicting scenes from 'Alexandria': Alexander the Great on horseback with a saber, a lion guarding the palace, and a winged monster. In 1709, a second floor was added above the chambers with a Cross-shaped chapel dedicated to the Not Made by Hands Savior.

In 1778, the building suffered significant damage from a fire, and in 1799, a third floor was added. In the 19th century, it became four stories high, and it was subsequently remodeled multiple times to accommodate various institutions. These changes stripped the complex of its architectural expressiveness, merging it with a two-story extension that distorted its appearance.

Research has shown that it is possible to restore the Archiepiscopal Chambers and the chapel to their original appearance. This requires dismantling the extension, restoring lost details and elements of the ancient buildings, including trimmed door frames and plastered tiles from the 16th century.

From 2014 to 2018, a large-scale reconstruction of the building was carried out. This included reworking the brickwork of all floors, door and window slopes, restoring inter-floor and attic ceilings, roofing, windows, and facades, as well as recreating the metal cross. Restoration work was done on the walls, ceilings, staircases, repairing cracks in the walls, finishing the ceilings and walls, restoring interiors and canopies, and restoring the foundation and plinth masonry with the replacement of individual stones and sections.
