№067 — Sentry box (Palazzo Madama, the Senate)
A sentry box next to Palazzo Madama, named for Margherita d'Austria, "la Madama", who received it in usufruct after Alessandro de' Medici died in 1537 and where the Senate has sat since 1871. The gold S on the panel is the Senate’s emblem, a registered trademark. I assume two carabinieri take turns and the one inside is winning. RR
