Route through the rooms
The museum display is on the first and second floor of the gate, and is divided in ancient, medieval and modern sections. It is made up of double-sided information panels, with texts in English and Italian, indispensably supported by colour drawings and photographs.
This room is situated in the East tower and contains a model of the Ardeatine Fortress, a military work designed by Antonio da Sangallo the younger (1483-1546) to reinforce the circuit of the walls. It is considered a masterpiece of Renaissance military architecture, and is still visible from the West of the arches on Via C. Colombo. High up on the walls charcoal drawings can still be seen, possibly preparatory sketches of various scenes, subsequently created in the frescoes and sculpture of the Porta S. Sebastiano, on the occasion of the progress of Charles the Vth in 1536.
