12. Upside Down House
Prepare for a mind-bending experience at the Upside Down House in Weisenweg, Germany. As the name suggests, everything inside this art installation is, well, upside down! Toilets on the ceiling and lights on the floor create an intriguing yet dizzying environment.
Visitors can’t stay inside for too long due to the disorienting effect, but they’ll leave with unforgettable photo ops and a renewed appreciation for gravity’s pull.
