Pelletta Palace
54, Via Varrone

Gothic building formerly belonging to the Pelletta family, bankers in the Aosta Valley, Savoy and Cologne in the 13th and 14th centuries. Completely renovated interior, it still bears numerous arches which are typical of the local tradition in the windows of its facade. It is traditionally known as "Pilate's house" perhaps due to the fact that nearby was one of the Stations of the Cross in the popular celebrations of the Passion.
