Gomenizza 81 | Viale del Parco Mellini, 00136 Roma - Monte Mario, ,
Monte Mario is the highest (139 m) hill of Rome.
The current name, according to some theories, comes from Mario Mellini, a cardinal who around the middle of 15th century owned there a villa and several hamlets.
On the hilltop, now occupying the site of the 15th century Villa Mellini, is the Monte Mario Observatory, part of the Rome Observatory, and the Museo Astronomico Copernicano.
