The Aventine Keyhole is a small but memorable Rome moment: a perfectly framed view of Saint Peter’s Basilica through a tiny keyhole.

Why it’s worth visiting

It is playful, surprising and very Roman: a small secret that turns into a memorable visual experience.

Best time to go

Morning, late afternoon or after visiting the Orange Garden.

Estimated time

10 to 20 minutes.

Insider tip

Free.
