It is a characteristic round tower built on the hill over hanging the town, using the ruin of Roman buildings; dates back to the first Saracen invasions and probably was used as a look out and a fortification, later on under the Norman domination it was transformed into a mill and some millstones are still on the first floor.

An old refrain which is singing up to now in the threshing floor in Sicily, tells this:

Between Trecastagni and Pedara,
There is a wind mill that grinds,
Grinds half burden in a week

This demonstrates the great notoriety of this mill, located in a place that is not at all grain, technical qualities for the grinding were not recognised to and therefore the ridiculous production remembered in the folk song.

Towards the end of the XVI century it was a private estate, the owners gave it to S. Alfio’s church, because, in the loop-holes existing on the top floor three muzzle loaders and a heap of stones to shoot as a joy during the days of the feast were put.

They are old pieces of artillery found in different periods during the digging of the vineyards, remaining perhaps of the battles between the Aragones and the Angevins along the Jonio cost.
