That one website that finds old maps of any place

Why it's the pick

OldMapsOnline searches historical maps from libraries around the world by place and year, and lays each one over today's map so you can compare. Searching and viewing are free without an account, but the free tier shows ads and caps extras like favorites and advanced search (membership from $2 removes them).
