The 40 Maps, History & What to Look For
The Gallery of Maps (Galleria delle Carte Geografiche) is a 120-metre corridor on the upper floor of the Vatican Museums decorated with 40 large topographical fresco maps of Italy and its surrounding regions, commissioned by Pope Gregory XIII and painted by Ignazio Danti between 1580 and 1583. It sits between the Gallery of Tapestries and the Raphael Rooms on the standard visitor route. The maps cover the entire length of both walls. The ceiling above — equally elaborate, depicting scenes from the early Church — is one of the most overlooked painted surfaces in the Vatican. Photography is permitted. Allow 20–30 minutes.
The Gallery of Maps is one of the most photogenic and most immediately accessible spaces in the Vatican Museums. Unlike the Sistine Chapel (where you cannot photograph) or the Raphael Rooms (where the significance of the figures requires explanation), the Gallery of Maps rewards any visitor who simply walks its 120-metre length and looks carefully at the walls and ceiling. The maps are beautiful as images and historically extraordinary as documents — they show Italy in the 1580s, before the current political map existed, at a level of topographical detail that was revolutionary for the period.

The 40 fresco maps in the Gallery of Maps depict: the Italian peninsula divided into regions (west coast regions on the left wall as you enter from the Tapestries; east coast regions on the right wall); the major islands (Sicily, Sardinia, Corsica, Elba, Malta); the siege maps of papal territories; and maps of the port of Genoa and the environs of Venice. The maps are arranged so that the Italian peninsula faces itself across the corridor — regions facing their opposite coast. The large map of ancient Rome and a map showing the environs of the Vatican itself are among the most studied by visitors.
| Wall | Maps Depicted | Direction |
|---|---|---|
| Left wall (entering from Tapestries) | Western Italian regions: Liguria, Tuscany, Lazio, Campania, Calabria | North to south |
| Right wall | Eastern Italian regions: Veneto, Emilia-Romagna, Marche, Puglia, Basilicata | North to south |
| Both walls | Islands: Sicily, Sardinia, Corsica, Malta, Elba; port maps; siege maps | Various |
The maps are oriented differently from modern convention — in several cases, south is at the top rather than north. This was not unusual for 16th-century cartography. The topographical detail is extraordinary: individual mountains, rivers, towns, and ports are depicted, with tiny ships at sea, forests on hillsides, and place names in a flowing 16th-century hand. The maps reward slow walking and close inspection.
Among the 40 maps, the large panel depicting the city of Rome occupies a prominent position. It shows Rome as it appeared in the ancient period — the major monuments of Imperial Rome, the Tiber’s course, the seven hills — rather than the contemporary 16th-century city. It is displayed alongside a companion map of contemporary 16th-century Rome, allowing visitors to compare the two cities at a glance.
Several of the maps depict specific military and political events — the siege of Malta (1565), the Battle of Lepanto (1571), and scenes of papal territorial disputes. These are the most narratively complex of the 40 panels and repay careful examination of the inscriptions.
The ceiling of the Gallery of Maps is painted with 32 large scenes depicting events from the history of the Catholic Church, separated by elaborate grotesque decoration in the style of the ancient Roman decoration discovered in Nero’s Domus Aurea. The ceiling was painted between 1580 and 1585 by a team of artists including Cesare Nebbia and Giovanni Guerra. It is as detailed and elaborate as the walls below — but almost universally missed by visitors absorbed in the maps. Spend at least 5 minutes looking up.
The ceiling scenes are arranged to correspond thematically with the maps below: events that occurred in a particular region of Italy are depicted in the ceiling above that region’s map. This cross-referencing between map and historical scene is the Gallery’s underlying intellectual programme — history and geography unified in a single space.
The maps were designed by Ignazio Danti (1536–1586), a Dominican friar, mathematician, and the leading cartographer of his generation. Danti had already created the maps for the famous Guardaroba Nuova (wardrobe) in the Palazzo Vecchio in Florence for Cosimo I de’ Medici. Pope Gregory XIII brought him to Rome specifically for this project. Danti designed the maps based on existing surveys, written descriptions, and his own measurements — then supervised a team of painters who executed the frescoes. He completed the entire Gallery in three years.
The Gallery of Maps is on the upper floor of the Vatican Museums, positioned between the Gallery of Tapestries and the Raphael Rooms on the standard visitor route. You cannot miss it — the corridor is 120 metres long and immediately recognisable.
Allow 20 to 30 minutes for a satisfying visit — long enough to walk the full length, examine individual maps closely, and spend time looking at the ceiling.
Yes — photography is fully permitted in the Gallery of Maps. Flash and tripods are not allowed.
The Gallery of Maps is historically significant as one of the most ambitious cartographic projects of the 16th century — 40 detailed topographical maps of the entire Italian peninsula and surrounding regions, executed in fresco at monumental scale. It is also the most photogenic space in the Vatican Museums and the clearest demonstration of the Renaissance ideal of unifying art, science, and theology in a single programme.
The ceiling contains 32 large fresco scenes depicting events from the history of the Catholic Church, arranged to correspond with the maps below (events in a region depicted above that region’s map). It is as detailed as the walls but almost universally overlooked by visitors.
