Antrodoco (Sabino: Italian: 'Ndreócu) is a town and comune in the province of Rieti, in the Lazio region of central Italy. The name derives from the Latin Interocrea (between the mountains).
Antrodoco is located along the Velino river, in the confluence point of two apennine valleys: the Velino valley, at North, and the Rio creek valley (a tributary of Velino) at East. Both are highly suggestive valleys, so narrow that they form canyons with sheer rock over the river: the first canyon is known as Gole del Velino, the latter as Gole di Antrodoco.
Monte Giano, the mountain where Gole di Antrodoco is located, is known for a pine tree forest with the shape of the word "DVX" (Latin for duce) which was planted in 1939 and is visible from miles of distance.
Thanks to its position, Antrodoco has been an important transportation hub since the time of the Roman Civilization.
Antrodoco was crossed by the ancient Roman road, Via Salaria, and was the starting point of Via Caecilia. The same route is maintained by two modern state highways:
Antrodoco has a station on the Terni–Sulmona railway, with trains to Terni, Rieti and L'Aquila.
