Baelo Claudia was an ancient Roman town in Hispania, located 22 kilometres (14 mi) outside of Tarifa, near the village of Bolonia, in southern Spain.

On the shore of the Strait of Gibraltar, the town was originally a fishing village and trade link when it was settled approximately 2,000 years ago.

The study of its architectural remains shows that the Roman town originated at the end of the 2nd century BC, and from the beginning possessed a great wealth that made it an important economic center in the Mediterranean area.

The town was founded at the end of the 2nd century BC as a result of trade with North Africa (it was a major port for Tangier, in Mauretania Tingitana, for example).

Excavations have revealed the most comprehensive remains of a Roman town in the Iberian Peninsula, with extremely interesting monuments such as the basilica, theatre, market, and the temple of Isis.

The main building, located at the back, is the basilica, which served various purposes, especially as the seat of the courts of justice; and on the left side there were small rectangular stone structures: the shops, or tabernae.

The Junta de Andalucía has built a new visitor reception center (designed by the architect Guillermo Vázquez Consuegra)[8] and has carried out a Landscape Action Project in the Bolonia beach (written and executed by the Andalusian Institute of Historical Heritage between 2010 and 2013).
