A whiff of chlorine is virtually synonymous with taking a dip in a swimming pool. While it helps to kill off bacteria, it also serves as a subtle reminder that you are wading around in chemically treated water (if tasting the odd mouthful just isn't enough).

This section of the border wraps around Riehen in such a way that in 2006, the town's old swimming pool had to be demolished to make way for a tunnel connecting two German cities on either side. With the controversial roadway completed in 2013, the people of Riehen were quick to reclaim their territory.
"The citizens wanted their pool back and believed that a natural swimming pool would suit their interest in bathing, swimming and playing, just as well as a traditional pool," Christian Lupp, Recreation and Sports representative from the Municipality of Riehen tells Gizmag.
