Church of the Holy Trinity, Athens

[5] No further information about the church is known during the subsequent centuries, until the earthquake of 3 September 1705, when it suffered considerable damage, after which it is believed to have been repaired and its interior decoration renewed.

[6] In 1821, during the Greek siege of the Acropolis, it was severely damaged by a cannonball fired by the Ottoman defenders: two-thirds of the dome and the entire west wall, as well as the vaults above the narthex, collapsed.

[6] The technical committee assembled to examine the church initially concluded that it would be best if it were demolished and replaced by a new structure, but in the end, it was decided to restore and rebuild it as close as possible to the original.

At the instigation of the French scholar A. Couchaud, all interior non-bearing walls were removed, in an attempt to restore the church to its "original" state.

Some are placed individually amidst the masonry, but others have been used to form a frieze running on three sides of the building, with champlevé ornaments on white plaster, emulating contemporary Byzantine art.

[15] The present interior decoration consists of frescoes that were carried out as part of the mid-19th century restoration by the German artist Ludwig Thiersch, with the assistance of Nikiforos Lytras and Spyridon Hatzigiannopoulos.
