Rome's most famous optical illusion lives here

The Galleria Spada (Spada Gallery) is a small but exquisite art gallery in the heart of the historic center, just steps from Campo de' Fiori and Palazzo Farnese. It holds the Baroque collection of Cardinal Bernardino Spada, still arranged today in the old style of the quadreria (a picture-gallery hang, with paintings packed frame to frame). But the real star is in the courtyard: the celebrated Prospettiva del Borromini (Borromini's forced-perspective gallery), a brilliant optical illusion that fools the eye in the most surprising way.

It's a short visit but an unforgettable one, perfect for anyone who loves art, architecture and the perspective "tricks" of the Baroque.

In the courtyard of the palazzo, Francesco Borromini built a perspective gallery that appears to run roughly 37 metri long, with a life-size statue at the far end. In reality it measures less than 9 metri, and the statue stands just 60 centimetri tall: the shrinking columns, the rising floor and the descending ceiling create an extraordinary illusion of depth. It's one of the most famous perspective tricks in the history of world architecture. We've given it its own guide: Borromini's forced-perspective gallery.

The Baroque quadreria

Beyond the perspective, the Galleria Spada preserves the collection of Cardinal Spada across four richly decorated rooms, with the paintings hung in several tiers from floor to ceiling, just as they were in seventeenth-century aristocratic homes. Here you'll find works by sixteenth- and seventeenth-century artists (among them Guercino, Guido Reni, Titian and others), along with ancient sculptures and furnishings. It's a rare example of a quadreria preserved intact. We go deeper in our guide on what to see at the Galleria Spada.

The palazzo

The Palazzo Spada itself is worth a look too: the facade and the courtyard are richly decorated with stuccoes and statues, in an elegant, refined style. The palazzo is also home today to the Council of State (not open to visitors), while the gallery and the courtyard with the perspective are open to the public.

How much time you need

A visit takes just 30–45 minutes: enough to see the four rooms and admire Borromini's perspective. It pairs perfectly with Campo de' Fiori, Palazzo Farnese and a stroll through the historic center.
