The Montaione hills have been inhabited since ancient times. The Etruscans were amongst the first peoples to populate the area, followed by a period of Roman colonisation. The first reference to Montaione is made in a document dated 981 A.D., where it is mentioned as Mons Allonis, from the Longobard Allone, lord of Lucca. The first definite reference to Montaione as a walled town can be traced back to 1257. 

Collelungo is an ancient farming hamlet, known since Medieval times as a community from the area of Tonda, situated on an elongated hill from whence the hamlet derives its name (colle lungo = long hill) and overlooking the valley of Evola.

The present accommodation structure was opened in 1996 and since then has welcomed more than 7000 guests from all over the world.
