Guedelon Castle, France
Who says the age of castles is over? Take a trip back in time at Guedelon Castle in Burgundy, France, where a team of 50 craftspeople and laborers are currently using 13th-century building techniques and technology (think: horses) to construct an authentic castle from scratch, deep within a secluded forest. Visitors are welcomed from mid-March to early November each year. The project has been running since 1997 and hopes to reach completion in the 2020s.
