The rectangular space opposite the main door was added in the 16th century, perpendicular to the original one, forming a T-shaped room. This extension took place in 1568 during the rebuilding of the monastery's south wing by Rucsandra, the daughter of the prince Petru Rares, and her husband, Alexandru Lapusneanu. The new seat of the Abbot, again marked by a niche, is there, right opposite the main gate.
