Tabula Geographia Britanniarum

Maps of Roman Britain

The pages linked from this index provide access to the core of the website, a database of almost two thousand Roman sites, with detailed pages on every single military encampment, each civil settlement, all known Romano-Celtic temples and many Romano-British villas, industrial sites and other substantial buildings. These maps make use of varying levels of internet technology.

NGR LayerMap Index
(XHTML Image Map)
This standard 'compressed' image map of Britain contains links to a number of CGI maps (see below) but itself contains no special technologies.
British Celtic Tribes
(HTML Image Map with JavaScript 'RollOver')
This standard interactive 'image rollover map' shows the territories of the Celtic tribes who inhabited the British Isles before and during the Roman period. The Latin invaders retained the existing tribal borders and converted them into administrative districts, each with its own tribal civitas capital, where the local nobility were obliged to reside and become the districts administrating officers, performing civic duties and public building works often involving large amounts of their own cash.
The Notitia Dignitatum Map
(HTML Layered Division Map)
A map showing the Roman military establishments and garrison units based in Britain during the late-4th century. This map will open in a separate pop-up window.
The Antonine Itinerary Map
(HTML Layered Division Map with Interactive JavaScript Controls)
A map of Britain showing the road stations on fifteen separate itineraries recorded during the reign of emperor Antoninus Pius in the mid-2nd century.
The Southern Military Campaign Map
(HTML Layered Division Map with Interactive JavaScript Controls)
A map of Southern Britain showing the military campaigns of the first ten governors of Roman Britain, showing the forts, camps and road stations which have been positively dated to their period of tenure as the Propraetor Britanniarum.


These are the latest super-wizzy maps which employ 'server side' programming and SQL relational databases for data storage and retrieval. By performing all database extraction and code generation in PERL/CGI on our servers before sending the web-page to your browser, this method is PDQ! All future development of the RBO database will employ these technologies.

Roman Military Encampments
An interactive 'layer-map' showing every Roman military encampment in the province of Britannia, including the permanent legionary fortresses, cmpaign or 'vexillation' fortresses, auxiliary forts, small fortlets, temporary marching camps, signal stations, light-houses and practice works.
Romano-British Settlements
This interactive 'layer-map' avery type of Romano-British Civil settlement, ranging in size from the smallest defended road-station to the Romanised capital city of Britain.
Temples, Villas & Other Buildings
An interactive 'layer-map' showing every Romano-British Temple, isolated Farm-Building, mosaic-decorated Villa and solitary milestone in Rural Roman Britain.
Romano-British Industries
An interactive 'layer-map' of all the Salt Working sites, Pottery and Brick Kilns, and all of the Lead/Silver, Copper, Iron, Tin and Gold mines in the province.
The Full RBO
This map contains links to every place-name page in the RBO database and as a consequence may be slow to load in some browsers or on older machines as it generates a whopping amount (i.e.400+KB) of XHTML. It was the first map to encorporate Site Classes on the website.

For several years the RBO website has used 'client side' technologies which run on the user's web browser to build map pages for the Wonderful World Wide Web. This has meant using XML to store data and JavaScript to perform all HTML code generation and programming, accessing the database through use of their powerful DOM-based amalgam AJAX.

However, processing large amounts of data 'client side' on your web browser significantly effects browser performance. For this reason these maps will no longer be supported. If you have 'bookmarks' or 'favourite' links to these maps it is strongly suggested that you replace them with links to the new technologies detailed above.

You have been warned!

National Grid Reference Index
A pictorial index page of every 100km square grid in the Ordnance Survey national mapping system; each grid square may be expanded to show a 100 by 100 kilometer square section of the British Isles in the form of an interactive 'layermap' allowing users to select whatever class (or classes) of site they wish to view.
Roman Military Encampments
An interactive layermap of all known Roman Military encampments in Britain, including all strategic legionary fortresses, campaign or 'vexillation' fortresses, auxiliary forts and fortlets, temporary marching camps, watch towers, signal stations and military practice works.

If you like our layermaps, this page allows you to generate a layermap to your own specification, showing as much or as little site detail as you wish.
Every Active Page in RBO
This layermap is not interactive, but its scripting generates a large amount of HTML which may cause your browser to stutter.
