Sansepolcro (anciently Borgo Sansepolcro) is the most densely populated town of Val Tiberina. The foundation of town dates back to the 10th century; according to the local tradition they were Arcano and Egidio, two pilgrims who, returning from the Holy Land, carried some clay of Jesus grave (sepolcro, in italian language), and founded here a convent. The abbey is cited since 1012. Around the abbey developed, subsequently, the nucleus of the city center that, in the 14th century, reached the current shape. Today, in the place of that abbey, there is the cathedral of Sansepolcro, beautiful church with Romanesque and Gothic features. The town has conserved nearly unchanged the aspect it had in the Middle Age, and now it is enriched with later buildings, among which we remember the church of Santa Maria delle Grazie, founded in 1518, in whose interior can be seen remarkable examples of the local tradition of the wood carving.
