On 2008, the municipality of Linguaglossa has planted a tree in Piazza dei Vespri in honor of Calogero Marrone, a man who moved from Sicily to Varese, and who has been acknowledged Righteous Among the Nations by Yad Vashem in 2013.
The ceremony was held on the 27th of January, on the occasion of the International Holocaust Remembrance Day, in the presence of the mayor, the students of the local high school and a man who was deported in Mathausen.
