The Arkazhy Monastery was one of the most important monasteries of medieval Novgorod Republic. All that remains of it today is the Church of the Assumption of the Mother of God, which is visible on the road out to the Yuriev Monastery. The foundations of the medieval monastery were excavated by Soviet archaeologists in 1961.
The monastery was founded by and takes its name from Arkadii, who founded it in 1153 prior to his being elected bishop of Novgorod (1156–1165). He initially built a wooden church to the Assumption. This church was subsequently rebuilt in stone in 1188 by Simeon Dibakevits and was consecrated by Archbishop Gavriil (1186–1192) the following year. Other boyars, including several posadniks, helped add to the monastery over the centuries. In 1206, Posadnik Tverdislav Mikhailovich built the Church of Simeon Stylites over the gates of the monastery. In 1395, Isaak Onkifov had the Church of St. Michael the Archangel rebuilt in stone, and it was overhauled in 1407 by Posadnik Yuri Dmitrievich and his cousin Yakov.
In addition to patronizing the monastery, at least two posadniks, in fact a father and son, became monks there: in 1206, Posadnik Mikhailko was shorn in the schema, the highest level of Eastern Christian monasticism, in the Arkazhsky Monastery and died there, having taken the monastic name Mitrofan. In 1222, his son Tverdislav was also shorn a monk in the monastery after he had taken ill.References:
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
