The nave of the catholicon was decorated with iconography in 1811 and the sanctuary in 1818 by the iconographers Veniamin, Zacharias and Makarios. The decoration was completed in 1841 with iconography of the narthex by the iconographers Ioasaf, Nikiforos, Gerasimos and Anthimos. The altar, the iconostasis, as well as other features of the temple, date back to this era. The iconostasis in particular, which depicts scenes from the Old and the New Testaments, is carved wood, covered with golden plating and is considered one of the most important post-Byzantine iconostases on Athos. The catholicon also has two chapels, a vestibule and a porch, added in 1845 by Ecumenical Patriarch Anthimus VI of Constantinople, a previous Esphigmenite monk.
