The British Museum houses a huge collection of artifacts from around the world. Almost every major civilization is represented here, from Babylon to Rome to Easter Island. Even the most jaded teen will find something to “wow” about, whether it’s the Rosetta Stone or a mummified cat from Ancient Egypt. You’ll probably spend about two hours roaming the halls, after which the kids will have been sufficiently impressed, but be ready to go. If you only visit one truly formal museum, this is the one you really need to get your teens interested in world history.
