# Sant'Ignazio, Rome > Sant'Ignazio is a 17th-century Jesuit church five minutes from the Pantheon, famous for Andrea Pozzo's optical illusions. Its flat nave ceiling becomes a bottomless sky with St Ignatius ascending, and the dome over the crossing is actually painted on a flat canvas. Entry is free; 20–30 minutes is enough — the trick is to stand on the marble disc in the floor.

It was never built. In **1685** Andrea Pozzo filled the gap with a **dome painted on a flat canvas** about 17 metres across, complete with drum, windows and coffering. From a second disc in the floor near the crossing, it looks entirely three-dimensional; plenty of visitors refuse to believe it isn't real. Walk on towards the altar and the illusion breaks, revealing a flat picture. ## Pozzo's ceiling In **1685–1694** **Andrea Pozzo** painted the **flat nave vault** with the **Apotheosis of St Ignatius**, a masterpiece of **quadratura** — illusionistic architecture. Painted columns and arches continue the real walls so that the roof seems to open into the sky, where Christ sends light to St Ignatius, who beams it to the four continents at the corners: Europe, Asia, Africa and America. The illusion works from **one spot**: a **yellow marble disc** set into the floor mid-nave. Stand on it and look up — everything lines up perfectly. Step a few metres away and the columns start to tilt. A large **mirror** in the nave makes viewing easier. ## About the church **Sant'Ignazio di Loyola** was built in **1626–1650** beside the **Roman College**, the Jesuits' main school in the city, and dedicated to the order's founder soon after his canonisation. The architect was the Jesuit **Orazio Grassi**. Outside, the little rococo **Piazza di Sant'Ignazio** by Filippo Raguzzini (1727–1728) is laid out like a theatre, its three curving houses like stage wings facing the church. ## Who was Andrea Pozzo? **Andrea Pozzo** (1642–1709) was a Jesuit painter and architect from Trento and the great master of Baroque illusionistic perspective. His treatise on perspective in painting and architecture taught artists for over a century, and he also designed the St Ignatius altar and the trick corridor at the nearby [Gesù](https://yesgo.io/italy/rome/church-of-the-gesu). ## What to see - **Apotheosis of St Ignatius** — viewed from the yellow disc mid-nave. - **The fake dome** — viewed from the second disc by the crossing. - **The nave mirror** — for comfortable viewing. - **Tomb of St Aloysius Gonzaga** — right transept, by Pierre Legros. - **Piazza di Sant'Ignazio** — a rococo stage set. - **The Roman College** — the former Jesuit school next door. > **Look back at the square** As you leave, turn round: Raguzzini's little piazza is a rococo theatre, the houses' curving fronts like scenery and the church steps like the stalls. Romans joked it was the best stage in town. ## How to get to Sant'Ignazio 1. Walk from the [Pantheon](https://yesgo.io/italy/rome/pantheon) — 5 minutes east along Via del Seminario. 2.

Yes — it's free, five minutes from the Pantheon and one of Rome's most astonishing interiors; the fake dome impresses even people who don't care for churches. Twenty minutes is enough, and it's rarely crowded. Pair it with the Gesù, whose Baciccio ceiling also 'opens' into heaven.
