The Citelli Refuge belongs to the municipality of Sant’Alfio (CT) and has its name for the private owner who built it and gave it to the community. It was built during 1935 at an altitude of 1741 meters a.s.l. on the northeastern slope of Etna into the ancient caldera of Mount Concazze. The structure has undergone a recent restoration (2011) through the Etna Park involvement that cited it among its Base Points for excursions (base point number 15) since 1987.
