Mangana Monastery

Mangana (Greek: Μάγγανα) was one of the quarters of Byzantine-era Constantinople. Located on the easternmost edge of the Sirkeci peninsula in which the city is located, it housed an imperial palace, arsenal and several churches and charitable establishments throughout the middle and late Byzantine periods.

The quarter was located on the extreme east of the peninsula, directly above the Great Palace and between the ancient acropolis of Byzantium and the Bosporus strait, and took its name from a large arsenal for military engines (mangana). The site was closely connected to the nearby Great Palace, and several emperors constructed buildings there. Emperor Michael I Rhangabe (r. 811–813) owned a mansion there which was converted into a crown domain by Emperor Basil I (r. 867–886) and administered by a kourator. The position of [megas] kourator ([μέγας] κουράτωρ τῶν Μαγγάνων) also involved the supervision of imperial estates in the provinces, whose proceeds went to the upkeep of the imperial court, as well as to supplying military expeditions.

Emperor Constantine IX Monomachos (r. 1042–1055) built a monastery dedicated to Saint George (with cloister and surrounding garden), as well as a hospital, a palace, old-age homes, hostels, poor-houses, and a law school. During his reign, Constantine IX granted the "pronoia of Mangana" to Constantine (III) Leichoudes who would later become Patriarch of Constantinople. The term pronoia would usually mean that Leichoudes enjoyed the proceeds of the Mangana, but in this case its meaning is debatable. During the 14th century, Emperor John VI Kantakouzenos (r. 1347–1354) lived at Mangana as a monk for a period of time after his abdication in 1354.
