The city is located in the eastern part of Basilicata, on the border with the city of Bari and the extreme north-western part of the province of Taranto. It stands right on the border between the Murge and the Bradanica trench furrowed by the Bradano river. The Gravina di Matera stream, a left tributary of Bradano, flows in the deep natural ditch that marks the two ancient districts of the city: Sasso Barisano and Sasso Caveoso. On the other side there is the Murgia. The ancient districts called "Sassi", together with the cisterns and water collection systems, are the particular characteristic of Matera. These are original and ancient aggregates of houses excavated in calcarenite, the "Gravina". At the end of 1993 UNESCO declared the World Heritage Sites Sassi. It borders with the municipalities of Montescaglioso, Altamura, Miglionico, Laterza, Santeramo in Colle, Ginosa, Gravina in Puglia and Grottole. Moreover, with 388.14 km² of territorial extension, Matera is the largest municipality in Basilicata. Seismic classification: zone 3 (low seismicity).
