A mansio was an official overnight stopping place on a Roman road, kept by the state for officials and others on government business. It offered food, a bed and fresh animals. It is not the same as a mutatio, which only changed horses.
Key takeaways
- A mansio was a state-run overnight stop on a Roman road, used by officials and people on official business [1].
- Mansiones were about 25 to 30 kilometres apart, roughly a day's travel for an ox cart [1].
- Some British mansiones are known on real roads, including a probable four on Stane Street between London and Chichester [1].
- Our map does not show mansiones, because the dataset has roads only. Stane Street is 93.3 km in our data.
How a mansio worked
The word mansio comes from the Latin verb manere, "to stay" or "to remain". A mansio was an official stopping place on a Roman road, maintained by the central government for officials and others on official business [1]. It was the place where such a traveller passed the night [1].
These were substantial buildings, normally in the form of a villa, set up for rest and refreshment [1]. Guests were expected to show a pass to identify themselves [1]. At each one, keepers hired out light carriages and carried government dispatches [1]. The mansiones were part of the state messenger system, the cursus publicus, which relied on a network of stations along the main roads [2].
Spacing followed the day's travel. Ox carts could manage about 30 kilometres a day, and pedestrians a little farther, so each mansio was about 25 to 30 kilometres from the next [1]. Between two mansiones, the general rule seems to have been two smaller stops, the mutationes, where animals were changed [2].
Around a mansio other things often grew up. Private inns stood nearby for travellers without a pass, and forts and even whole towns sometimes developed on the same site [1].
Late in the empire, the costs of the system were charged to the people living along the routes [2].
An example from our data
Our map shows the roads, not the stops on them. The Itiner-e atlas that supplies the data has no layer for mansiones, bridges or milestones, so none are drawn.
Stane Street is a useful road to think about. In our data it runs for 93.3 km in 8 segments, between London and Chichester. Wikipedia lists a probable four mansiones along its route [1], and one of them, Alfoldean near Slinfold in West Sussex, was the subject of a dig by the television programme Time Team in 2006 [1]. Those stops are not points on our map, and the road itself is only 0% certain in this dataset.
Further north, Watling Street is 352 km in our data. You can see the roads of all four UK nations on the UK page. Use the how to read the map notes to understand the certainty colours.
The thing people get wrong
A mansio was not a hotel for anyone with money. It was a state facility for people with a pass, and ordinary travellers could use private inns that stood near the mansiones [1]. The English word "mansion" is likely to come from it, but the two have quite different uses [1].
Mansio vs mutatio
Frequently asked questions
What is the difference between a mansio and a mutatio?
A mansio was an overnight stop with lodging. A mutatio was a changing station where animals or vehicles were swapped or serviced.
Could anyone stay in a mansio?
No. It was for officials and people on official business, who were expected to show a pass.
Are mansiones on the map?
No. Our dataset holds road lines only, so mansiones are not shown.
