The church is situated in Erechtheos and Erotokritou intersection in Plaka. It is a two-columned, cross-in-square church with an Athenian dome dating to the beginning of the 12th century. Fragments of Byzantine wall paintings are preserved in the interior. Stylistically they relate to other wall paintings in various churches of Attica such as the small churches in Pentelis Cave or Hagios Petros in Kalyvia dated to the beginning of the 13th century.
