Agioi Asomatoi, Byzantine church in Thiseio, Greece

Agioi Asomatoi is a small cross-in-square Byzantine church on Ermou Street, set about two metres below street level. Four monolithic piers carry an octagonal Athenian-type dome pierced by eight windows with slender columns and marble panels. Its walls use cloisonné masonry with porous stone from Megara, and two pseudo-Kufic terracotta frieze fragments remain on the west facade.

The church is dated by specialists Anastasios Orlandos and Arthur Megaw to the second half of the 11th century, based on its architecture, close to the Panagia Kapnikarea; it may have been founded by a local aristocrat or a senior Byzantine official and could have been the core of a small monastery. From 1880 it received large extensions, 4 m wide and 17.75 m long to the north and 5 m wide and 16 m long to the south. Restoration in 1958-1960 demolished these additions, partly rebuilt the north and south walls, entirely rebuilt the west wall, and excavation in the narthex revealed three tombs, inscriptions and Byzantine pottery.

The name Agioi Asomatoi, "Holy Incorporeal Ones", refers to the angels, and the church celebrates their feast on 8 November. It serves as a parish church of the Archdiocese of Athens. On the west facade, two terracotta plaques with pseudo-Kufic relief lettering are still visible, and the north door has a horseshoe arch.

The church is located in the Thiseio neighborhood and is easily accessible on foot, situated near other archaeological sites in the area. Visitors should check opening hours in advance since they are limited and may vary on different days.

The west facade still carries two terracotta tiles with pseudo-Kufic relief script, and the north door is framed by a horseshoe arch. These Islamic-style elements may point to a small community of Arab traders in Athens. Excavations during the 1958-1960 restoration also brought to light three tombs in the narthex, along with Byzantine inscriptions and pottery.
