Asturias56 has the name now -
Parco Colonnetti . I've got pictures of Idroscalo Turin, and they were going to be for another challenge - maybe not for a while now.
dook has the name of the airfield when it was in use -
Mirafiori, and the first airfield in Turin, built in 1910. The second airfield was where the Aeroclub are now based.
Fiat have a plant close by - the buildings with the loop test track, which is still present today. Fiat named the Fiat 131, the Mirafiori.
There used to be a very comprehensive history of flying in Turin on the Aeroclub website - only available now via the
way back machine. - this is the section about Gino Lisa and the Aero Club.
In June of 1921, the sports aviation section (S.A.T.) of the Mirafiori airfield was renamed at a moving ceremony to honour the memory of Gino Lisa, Military Gold Medal for Valour, a young man who had learned to fly there, volunteered for the war, and at 21 years of age gave his life for his country, shot down trying to protect a colleague.The S.A.T. thus became known as the “Aerocentro Gino Lisa”, a denominati***on which was later changed to the “Aero Club Gino Lisa di Torino”.
I'm going to give this one to dook as he named the airfield correctly. Well persevered, and over to you.
Edit to add:
On the 28th of March 1923, the day when the “Arma Aeronautica” (the Air Force) gained its independence from the Army, becoming an autonomous service, the military area at Mirafiori was named after Col. Carlo Maria Piazza (Busto Arsizio 1871 – Milan 1917), pioneer of military aviation (Military Pilot’s Licence No. 1) and decorated with the Silver Medal for Valour.
