The History of York website claims that you can explore York’s history from prehistoric to the present day and from what I’ve seen I think the claim is correct. There are Timelines, Trails, Themes, a What’s New section as well as audio tours. There is a tempting video trailer of the new History of York audio visual spectacular, introduced by Dan Snow, that is now available at the Yorkshire Museum.
The Yorkshire Museum also has a very interesting and informative website, that is well worth spending time on. A quick search on YouTube showed that the York Museums Trust has made a number of YouTube videos that are excellent. I’ve put a link to one below.
So if you have ancestors who lived, worked or played in the city of York or the county of Yorkshire here are some resources for you to investigate.
