Muttuchira lithic inscriptions are early Malayalam inscriptions (Vattezhuthu, Nanam Monum) on a granite tablet found in Muttuchira. The 'Muttuchira inscriptions' are inscriptions narrating the installation of the free standing cross and the Pahlavi-inscribed bas relief cross, the 'Muttuchira Sliva'. The inscriptions are on a rectangular granite slab in two sections, divided by a vertical line in between. According to Mr. T. K. Joseph [eminenthistorian], this inscription must be from AD 1581 or later. This tablet has been the subject of extensive research by many scholars. This granite slab was found on the western wall of the ground-floor room of the two-story building attached to the northern side of the old Church of the Holy Ghost. The upper story was used as the priest's home, and the ground floor was used as the sacristy.
