My morning run went via a 15th century dike to a 19th century dike, past remnants of Spanish 17th century forts and 20th century bunkers of the Atlantic Wall.
Only 14km for a serious timetravelsession.

Don’t tell your players what happened 200 years ago.
Let them live it. Show, don't tell!
Run a one-shot where they are the lost civilization.
Inspired by "The Inner Light" (TNG).
