Palazzo Assessorile, medieval palace, now an exhibition and conference venue in Cles, Trento, Trentino Alto-Adige

Palazzo Assessorile is a building in the center of Cles that began as a medieval stone tower and was expanded through Renaissance-era modifications. Three floors contain different spaces: the ground level was designed for storage, the middle floors served administration and private living, and the upper rooms are richly decorated with 16th-century frescoes.

The tower core dates from around 1200 and is first documented on 2 May 1356, when Iosio di Enrico di Sant'Ippolito bought a house-tower with walls from Giovanni di Arpone di Cles; it served as a visual signalling point and food store. Damaged in the peasant revolts of 1407 and 1477, it passed to the de Cles family, and Giorgio de Cles rebuilt it into the present palace by 1484, the year of the facade coat of arms. Bernardo Clesio left it in 1538 to his nephew Ildebrando, husband of Anna Wolkenstein, who commissioned Renaissance decorations.

The palace displays family symbols and emblems throughout its rooms, showing how the De Cles family connected power with artistic expression through painted walls and ceilings. The family's colors of white and red appear repeatedly in the frescoes, marking their presence in nearly every decorated space.

The palazzo stands between Corso Dante and Piazza Granda in the historic centre of Cles. The judicial functions moved in the 20th century to the facing Palazzo Dal Lago de Sternberg, now the courthouse. A restoration concluded in 2009 followed an earlier campaign of uncovering and restoring the paintings at the start of the 20th century.

The third floor bears inscriptions and carvings left by prisoners held there for decades, who scratched their names into wooden walls. These subtle marks tell personal stories from a lesser-known chapter in the building's use and are carefully preserved today.
