The property complex located in Valdurasca, called "Ex Polveriera", consists of a former army ammunition depot, easily accessible from the provincial road that goes from Via Montalbano towards Valdurasca and is connected with the limit of the Municipality of Follo.

It covers a total area of 22 hectares, divided into a rather extensive flat area and then into another hilly area that closes the space in a semicircle; a massive complex with rather sparse concrete and wood buildings hidden from view by the path.

Through an internal track it is possible to reach the deposits or "Casematte difensive": masonry rooms of rectangular shape with a variable surface, once used for the custody of armaments and war materials.

An entire area today is covered by forests and artificial lakes and vice versa in a general state of abandonment, as well as its buildings, with the presence of solid urban waste; due to this a fundamental reclamation is required.

The Municipal Administration proposes the recovery of the compendium in respect of the existing structures, allocating it to tourist, sporting and recreational activities.
