(horizontally) as the main hall of the cathedral, except that it has no apse area. With annexes the underground chapel has 13,668 square meters, with 155 meters by 92 meters. The gallery St.Andrew's Cave has 15,581 square meters (including annexes) with 143 meters by 118 meters. If a person walks through the entire underground gallery of the cathedral from west to east, he has to walk 300 meters in a straight line. The two large underground galleries together have approximately 30,000 square meters. The galleries are divided into: spaces including a main hall, other halls and rooms for events; an icon and religious clothing shop; a workshop (for carpentry, upholstery and metal work for example); a museum, gallery-exhibition, liturgical performance media shop; as well as storage rooms, a refectory, religious/sacramental objects and employees rooms. Initially instead of the underground room of St.Andrew's Cave, a car park was planned there. But this was becoming an inconvenience for the underground chapel, due to emissions from cars, the plan was abandoned. Thus, the car park will be arranged on the left side of the courtyard from the west. The St.Andrew's Cave gallery will host the Museum of Romanian Christianity. Under the cathedral chapel at a depth of 16 meters, will be arranged only technical spaces for installations. Also at this level, 42 crypts will be arranged for the patriarchs of Romania and four atomic bunkers. The chapel will have a liturgical program for the monastery (daily). Liturgical services in the cathedral will be held on Sundays and on important holidays. The Holy Altar of the chapel is dedicated to Saint John James the Chozebite and Daniil Sihastru, because they both lived a part of their lives in the cave. Saint John James the Chozebite (Hosevite) became a monk at Neamt Monastery and soon after his conversion he moved to the Holy Land where he lived near the downstream of the Jordan river, near Jericho. Toward the end of his life, he lived in the wilderness of Choziba at the Saint George Monastery. In 1992 he was declared a saint by the Romanian Orthodox Patriarchate and in 2016 he was officially recognised as such by the Greek Orthodox Patriarchate of Jerusalem. The Church celebrates his feast day on 5 August. Daniil Sihastrul (or Daniel the Hesychast) was a renowned Romanian Orthodox spiritual guide, hermit, hegumen of Voroneț Monastery and advisor () of Stephen the
