ChiusureAncient village , on the top of which survived the rearranged rests of an ancient castle which is part of Saint Angelo in Luco. It is situated on a high slope which, in the past, was covered with woods, where the Monastery of Monte Oliveto Maggiore was erected, into the village of Chiusure, about 1 km far. The antiquity of this settlement is testified by the fact that its church of Saint Angelo in Luco, at the beginning of the VIII century, was the object of a dispute among the bishops of Siena and those of Arezzo. It is also mentioned in the approval bill of the Congregation of the Olivetans, and of their major monastery, where it is said that it was founded in the district of Saint Michele in Luco’s parish. From some ancient sienese memoirs, we know that Antonio di Meo Tolomei bought Chiusure in 1333. It seems superfluous to add that the founder of the Congregation of Monte Oliveto belonged to the same sienese family of Tolomei and that the hillock of Acona, where the first hermitage was erected, was wooded.
