There are few traces of Free Territory of Trieste, only one can be considered a sort of Memorial. Below you will find some:
This is positioned at the Castle of Miramare in Trieste. (Since 2004)
This is positioned in Opicina (Trieste) at the entrance of the "Soldiers Field" sport complex built by the Us Troops, recently renewed (2012).
Here below a plaque remembering reconstruction of the Area, probably before 1950.
