It emerges from the dense chestnut woods that were once his wealth.
It is perhaps the oldest village in the Municipality of San Benedetto Val di Sambro.
It was a fortified castle on the Apennines on the way to Florence. Scholars cite a 1904 document where the land of Aqualto is already mentioned. Its isolation among the woods at over 700 m of altitude has allowed it to partially preserve its original appearance, of wild beauty, formed over the centuries.
Stone walls, roofs of slabs, dated architraves remain many buildings back in time, to the sixteenth century.
The ancient church suffered serious damage from the September 2003 earthquake and must be restored. The bell tower, in a different spire design, dates back to 1914. Next to the church, the well-known Cà di Bastiano, a building variously dated, characteristic and now unique in the Bolognese Apennines due to the entrance to the balcony, is worth mentioning. the presence of a gallery covered with slabs to protect from bad weather.
The well executed restoration made it possible to enhance this architectural monument of rare beauty.
At the foot of the slope and towards the church, an ancient fountain (the date carved in the friable sandstone is illegible) from the spring water boasted as the lightest and freshest of the Municipality. At Qualto, even dryers are lit for the winter preservation of chestnuts.
Two hundred meters higher, the Rongrino farm obtained, as the toponym bears witness, clearing the flat ground and the more gentle slope, has been transformed into ungulate farms (deer, fallow deer, mouflon). Recently the Municipal Administration has taken steps to carry out a project to enhance the village by restoring the paving slabs of the square and the alleys and alleys of the historic village.
