The Museo Etnografico Tiranese (MET) is an ethnographic museum in Tirano, a town in the valley of Valtellina in the Lombardy region (province of Sondrio).

The collection of the Museo Etnografico Tiranese is located since 1990 in the Casa del Penitenziere (Penitent's House), an 18th-century Palazzo nearby the Basilica Madonna di Tirano.

The exhibition area is extended over three floor levels and a cellar room, showing a cross-section of the historic working and rural living environment of the Valtellina.

The donation is to consider as a political act with the aim to strengthen the followers of the French party in the Valtellina during the conflicts of the Bündner Wirren, part of the larger Thirty Years War.

In the year of 1993 the Museo Etnografico Tiranese has also been associated with the Centro Provinciale di documentazione sull'emigrazione, which was founded to study the Italian migration movement with a focus on the emigration from the province of Sondrio.

Therefore, the collections of the museum contain more than 1.600 letters from Australia in originals and in copy which describe the new life of the emigrants, and generally are a source for communication structures between the new and the old home land.
