Where are you going to find Roman ruins beside a breathtaking Nudist Beach? Only in Spain.
Baelo Claudia, right beside Bolonia beach: http://nudeinspain.com/nude-beaches/cadiz-tarifa-bolonia
It is an ancient Roman town. Lying on the shores of the Straits of Gibraltar, the town was originally a fishing village and trade link when it was settled some 2,000 years ago. Although prosperous at the time of Emperor Claudius, it went into a decline hastened by earthquakes and was abandoned by the 6th century.
