The MOA Museum is housed in a building of considerable historical and artistic interest: built in 1490 by the Order of Friars Minor Observant, as the Holy Trinity Convent, in 1550 it was enlarged and in 1620 the entire monumental complex was completed, which was to be used in different ways over the following centuries.

In 2012, this facility was used as a museum, and the MOA, Museum Operation Avalanche, was opened here.

The permanent collection, which is divided into several rooms, contains remnants and findings from Operation Avalanche, while along the corridors visitors can walk through a significant photo exhibition, in which some moments of the Allied landings are filmed.

There are two permanent historical itineraries: the exhibition of historical photographs from the private archive of the writer and historian Angelo Pesce, and the interactive multimedia room, where visitors can relive the main steps of the wartime events that took place in Piana del Sele.

The Italian, German and Allied objects, relics, weapons and uniforms that are preserved and exhibited here, in an area of around 1,500 square metres, were recovered during excavation campaigns in the area of the fighting by the Avalanche 1943 Historical and Cultural Association. The rest of the collection consists of donations or loans from private individuals and associations. The exhibits also include private diaries and official documents, which further contribute to the proposed museum narrative.

Lastly, there is the so-called 'emotional room', in which, through multimedia, visitors can virtually dive into the places of the narrated events. Two screens were installed here, a vertical and horizontal one, on which images and films of the military operation were projected. This kind of narrative approach results in a greater sensory and emotional involvement, leading to a high impact for museum visitors.

In addition, the MOA is a true creative space, where artistic activities, performances, exhibitions, dissemination initiatives, training, and the promotion of tourist itineraries take place.

Today, the MOA is an essential reference point for knowledge of the events of the Allied landings and, responding to the objective of giving greater visibility to the themes linked to the contemporary history of the territories crossed by Operation Avalanche, it also aims at consolidating relations between cultural bodies and institutions in order to create a museum system spread throughout the regional and extra-regional territory, thus encouraging debates and discussions with national and international museum entities.
