Having the statue of the angel behind you, you will see a stairway on your right (pay attention: the staircases leading to the terrace are only one way. You can’t walk downstairs from the same staircase you came up!). Climb down the stairs that lead to the Paolina Hall (Sala Paolina) (official numbers 22 &14). Going downstairs pay attention to the steps: they are narrow and slippery and might be dangerous. Tip1: The 5th level of the building offers the opportunity of admiring a 360 ° panoramic overview of Rome; in fact, you can walk on the so-called "giretti" running along the perimeter of the structure. Tip2: There is "Le Terrazze del Castello", a cafeteria located along the "uncovered walk", where you can sit and enjoy a coffee with one of the most incredible vistas of the Eternal City.
