Monte Cairo (1,669 m) is a mountain in Lazio[1] (in the province of Frosinone), overshadowing both the Abbey and the town of Monte Cassino, 5 kilometres to the south.[2] The ancient 'Mons Clarius' was so called because originally a temple dedicated to Apollo (Clarius) stood where the Abbey of Monte Cassino now stands. The Monte Cairo is the main peak of an isolated mountain range that extends eastwards for about 16–18 km from the Alta Valle del Melfa, the road from Rome to Naples.[citation needed]
Geology
Monte Cairo is situated in Italy's central peninsula which is dominated by active extensional tectonics.[3] The geological structure is of limestone[4] dating from the Cretaceous period[5] and due to its position in the region the formation is known to experience earthquakes and subsidence.[6]
The tops of the mountains are barren, in contrast to the partially wooded sides.[clarification needed]
At an altitude of 1300 m and west of Monte Cairo lies the Monte Pozzacone Refuge, a property owned by the town of Colle San Magno and a suitable base for climbing to the top of Monte Cairo. Other peaks of the group include the Monte Obachelle (1476 metres) where there is a significant Karstic sinkhole, the Pizzo di Prato Caselle (1372 metres), and the Cimmaron Villaneto (1315 m).
