This might be the closest I've ever come to mentioning religion on this blog. In the interest of neutrality, if you know of interactive maps based on other religions, leave a comment with a link and I'll link it to this post.
The website About-Jesus.org hosts six interactive maps tracing stories from the New Testament of the Bible. The maps were created using Google Maps. The list of maps includes Paul's 1st, 2nd, and 3rd mission journeys, Paul's journey to Rome, a map of Jesus's ministry, and a map of the cities mentioned in the book of Revelation.
Applications for Education
These maps might be useful for anyone teaching a course on religion. The maps also provide a model that students can use to create their own maps of religious stories.
