This interactive map charts over eight centuries of battles, sieges, raids and campaigns fought on Welsh soil and beyond from the Dark Age kingdoms of the seventh century to the final revolt of Owain Glyndŵr in the fifteenth century.

Every pin marks a precisely researched location where Welsh history was decided by force of arms. Each location includes a description of what happened, who fought, and why it mattered.

Every location uses a traffic light confidence system:

🟢 Green — Well documented site. Location confirmed in historical sources and precisely identified.

🟠 Orange — Approximate location. The general area is correct but the exact site remains uncertain or unconfirmed.

🔴 Red — Disputed or unknown. The site has never been firmly identified. The location given represents the best available geographical reasoning based on the historical record and landscape evidence.

This honest approach distinguishes between what we know, what we think we know, and what remains genuinely lost to history making this map a serious research tool as well as an engaging historical journey.

Offa's Dyke the great earthwork that drew the line between Wales and England is mapped in full as a separate feature running its entire length from Prestatyn to Chepstow.

This is a live ongoing project updated in real time.

New locations and layers are being added regularly. Every update is reflected automatically through the link provided the map you see today will be more complete tomorrow.

Over 130 locations are planned covering 616 to 1421 AD. The map grows daily until the full timeline is complete.

A new approach to sharing history.

I believe history should not live only in books and academic journals. It belongs on the landscape where it actually happened accessible to everyone regardless of their background or level of historical knowledge.

As a digital historian I have spent years finding new ways to share the past through technology. This map is the result of that approach applied to one of the most extraordinary and least known stories in British history eight centuries of conflict in medieval Wales.

By combining meticulous historical research with modern digital mapping technology I have tried to put that story back into the ground where it was fought making it navigable, explorable, and felt rather than simply read. Every pin on this map represents hours of research, careful geographical reasoning, and a genuine passion for bringing the past to life in a way that anyone can access and explore.

This is not a replacement for traditional scholarship. It is a companion to it a living document that grows, evolves, and invites everyone to engage with the past in a genuinely new and immersive way.

History made accessible through technology. That is what I am trying to do. I hope this map goes some way towards achieving it.
