My grandmother gave me a documentary series about Ireland and its history and the narrator spoke of this website: http://www.mythica....com/ancientsites/
The documentary itself is about 15 years old, and at the time of its publishing this website was brand new. It looks slightly outdated now but new updates are still added to it on occasion.
The link should bring you to a list of ancient burial and historical locations around different counties in Ireland. I find them to be stunning and fascinating.
The site is slightly difficult to navigate so here are a few other links as well... http://www.mythica...and.com/mythology/http://www.mythicalireland.com/art/http://www.mythica...ites/stonemap.htmlhttp://www.mythica...and.com/astronomy/
