Peristyle — The Colonnaded Garden of the Roman House

What Was the Peristyle?

The peristyle (Latin peristylium) was a colonnaded courtyard garden set at the rear of larger Roman houses. A roofed walkway supported by columns — the portico — ran around all four sides of an open central garden, the hortus, which was typically planted with shrubs and flowers and adorned with fountains, pools and statues. It was the private, restful half of the home, reserved for the family rather than for business callers.

The idea came from Hellenistic Greece and entered Roman domestic architecture from around the 2nd century BC, as Rome's elite grew wealthier and absorbed Greek tastes. The peristyle replaced the older, purely practical kitchen-garden hortus with a space designed for pleasure, shade and display.

Peristyle vs Atrium

A Roman house was built around two courtyards with very different characters. Understanding the contrast explains the whole layout:

Feature	Atrium	Peristyle
Position	Front of the house	Rear of the house
Origin	Old Italic tradition	Hellenistic Greek influence
Centre	Impluvium rainwater basin	Open garden (hortus)
Surrounded by	Walls and small rooms	A colonnade / portico
Purpose	Public reception, status	Private leisure, greenery
Atmosphere	Formal, business-facing	Relaxed, family-facing

Visitors entered through the atrium, where the tablinum offered a sightline straight through to the peristyle beyond — but only invited guests and the family passed into the garden itself.

Inside the Peristyle Garden

A wealthy peristyle was a carefully composed outdoor room. Typical features included:

• A portico — the shaded colonnaded walkway running around the garden.
• The hortus — the planted central garden, sometimes formally laid out in beds.
• Fountains and pools — moving water for coolness and sound, fed by the town's aqueduct.
• Statues and herms — marble or bronze sculpture among the planting.
• Frescoed walls — often painted with garden scenes to extend the greenery visually.
• Dining and living rooms opening onto the colonnade to enjoy the view.

The Peristyle at Pompeii

Pompeii preserves some of the finest peristyles in the Roman world. The House of the Vettii is the classic example, its garden replanted and ringed with marble statues and fountain figures, showing exactly how the space looked and worked. From a simple back-garden hortus, the peristyle had become the showpiece of the elite Roman home — a private green sanctuary that married Greek elegance with Roman comfort.
