The Martani Mountains extend evenly from south to north for about 35 km between the provinces of Perugia and Terni. They border to the east on the Umbrian Valley and Valserra, to the west on the valley of the Tiber and that of the Naia and to the south on the Terni basin with the Nera River. The chain of Martani Mountains is surrounded by important cities and historical centers: Montefalco and Foligno to the north, Spoleto to the east, Todi, Acquasparta and Sangemini to the west and Terni to the south. There are also numerous ancient finds and archaeological sites. The most important is Carsulae.
The tops of Martani Mountains are mostly rounded and covered with grass. The main are (from N to S): Monte Martano (1094 m) - Monte Capoccia Pelata (1054 m) - Monte Forzano (1086 m) – Cima Panco (1013 m) - Torre Maggiore (1121 m) - Monte Torricella (1054 m). The vegetation predominantly consists of oak and, in higher areas, beech. The Martani are full of caves, sinkholes and water erosion inside the sinkholes. The Martani are part of the Umbria-Marche Apennine: they are a well-defined geomorphological and lithological entity described as a system of folds and thrust faults arranged to form an arc in eastern convexity. The summit areas emerge micritic limestones: you are placed in an environment of pelagic sedimentation from the Lower Jurassic, ie from 190 million years ago. Along the ridge one can observe interesting karst morphotypes, formed by the corrosive action of rainwater on limestone, such as sinkholes, diffusely present along the chain (The Tifene, Corva of Mezzanelli, Pozzale, etc..), to the west of the same and karst plains such as Casetta San Severo. Near the summit of Monte Martano a strong humanization altered the mountain landscape. In this place, considered strategic for position, exposure and altitude, a considerable number of radio and television repeaters were placed.
