The Omurtag's Tarnovo inscription is an inscription in the Greek language, engraved on a column of dark syenite, found in the SS. Forty Martyrs Church in Tarnovo, Bulgaria. The inscription was found in 1858 when Hristo Daskalov, from Tryavna, managed to visit the church (which was converted to a mosque at that time) and to make a replica of the inscription.
Along with the Chatalar Inscription, the Tarnovo inscription testifies for the active construction during the reign of Kanasubigi Omurtag (r. 814–831 CE).[1][2] It is assumed that the inscription was made in 822. Historians are uncertain about the original location of the inscription (probably Pliska) and the location of the "new home on the Danube", for which the inscription was created. Contenders include Silistra, the village of Malak Preslavets, or the island of Păcuiul lui Soare (now in Romania).
