Does anyone know of an interactive map that shows European borders across the ages?

I'm dreaming of something like google maps that lets me zoom into locations and see if the village changes country over time. My genealogy has lead me to look at Sardinia and the Austrian empire but I don't posses the local knowledge to know if any other locations changed between a specific event and now. I'm not asking about specific locations but a tool I can use more generally to go and find new sources.
