Mercator-e Project

The main research objective of this project is evaluate the changes in the transportation historical networks evaluating their connectivity and the costs and times of travel.


This is the webpage of the Mercator-e Project. Here you'll find all the documentation about this project: description, objectives, methodology, results, dissemination and historical networks available to download.

Some of the data produced in this project has the aim to answer important historical questions about the unequal development of the Iberian peninsula territories. Questions like:

  • How was the mobility and the transport costs & times in the Iberian Peninsula from Roman times until the XIXth Century?
  • How and why do centers of economic, political and social power evolve and change? How are these structural changes reflected in the transport network of a territory?
  • How did the political decisions affect the transportation networks over the centuries? And which was their economical impact?

The knowledge on Iberian Transportation Networks for the community

In this project you'll find a place where download maps and files about Iberian Transportation Networks. If you want to collaborate you can send us your data and it will be upload in our system (fully credited, of course!)

Data and Maps

To document, digitise and publish all the transportation roads of the Iberian Peninsula from Roman Times until the XIXth Century is a huge enterprise.

Although this project is focused to work on a wide geographical scale (the entire Iberian Peninsula), we are looking to provide the most possible detailed information.

One of the main dissemination objectives of this project is offer to the wide scientific and general society a free source of information about historical networks. For that reason, if you detect a lack of information of one territory or you have been developing a research and want to aggregate it to our network repository (with your credits) we'd be very grateful if you get in contact with us.

Some international researchers has kindly provided their data to this project in order to make all of their research more available to the entire community and to increase the general information about the Iberian historical transportation networks.

Do you have comments or data to share with us?

This is an open to community project. This means that we more than welcome contributions and comments about our project, our data and our results. We are very interested in creating a dialogue with other specialist in Historical networks mostly (but not only) in the Iberian Peninsula. So, if you have data about roads that you want to publish in our networks (fully credited of course) please write us and we will upload them.
