The church of Agia Paraskevi, on 6 Dioskouron Street, is built in the courtyard of an old mansion, on the way to the Acropolis. The church belongs to the Greek Old Calandarists, a religious group which is not in communion with the official Greek church. The church also saves religious icons and ceremonial items from the similar church of Agios Athanassios of Vlassarou, which was demolished.
Greek Old Calendarists, also Genuine Orthodox Christians are groups of Old Calendarist Orthodox Christians that remained committed to the traditional Orthodox practice and are not in communion with most of the other Orthodox churches such as the Orthodox Church of Greece or the Patriarchate of Constantinople. The split began with a disagreement over the abandonment of the traditional church calendar (also called the Julian calendar) in preference to the adoption of the Revised Julian calendar which is similar to the papal Gregorian calendar and over other liturgical reforms that were introduced.
The church celebrates on July 26th.
