The goal of the project funded by U.S. Ambassador’s Fund For Cultural Preservation is to preserve the most critically endangered parts of the late medieval Saint Sargis (Saint John the Baptist) Church in Meghri, Armenia, which is an outstanding and exceedingly rare example of the Persian-Armenian style design. Its magnificent interior frescoes are unmatched in the Caucasus and the Middle East. Currently the church, and especially the frescoes, which entirely cover its interior surface, are in need of urgent intervention: specifically, alleviating water damage to the murals and the underlying structure; repairing and installing proper drainage; preserving and restoring cover tiles and mural segments critically in need; and installing climate control and thermal humidity control systems to protect and monitor the frescoes’ environment.
