Europe has almost countless castles and palaces, of all sizes, and all with an interesting history. The choice is rich: look for adjacent chapels, fortresses, and gardens to explore, too.
Many former royal abodes are now art and history museums and host festivals and historic reenactments; others lie in mysterious ruins. Some are still inhabited by royals or noble families! Others have become luxurious hotels. Guided tours and children’s programming abound, so the past is made accessible to everyone. You can also wander freely, imagining days gone by.
