The catholicon, which is dedicated to the Ascension of Christ, was built between 1806 and 1810 by the abbot Theodoritos on the site of an earlier catholicon and in the manner of Athonite churches. It was consecrated by Patriarch Gregory V in 1811. The construction of the catholicon was greatly aided by personal donations from Bishop Ignatius of Kassandreia. The temple itself is spacious and majestic and bears eight domes on its lead-covered roof, the central dome being the largest. The marble used for its construction was transported to Athos from Tinos, the place of origin of the church's architect, Paul.
