It is located in Ajo in the municipality of Bareyo. The Convent of San Idelfonso was ordered to be built in 1588 by Alonso de Camino, captain of Felipe II in Flanders. Currently, the convent is in ruins, although in recent years it was decided to restore and use the Convent of San Idelfonso as an important Romanesque Interpretation Center. The church is kept in good conservation. Check first that it is open. There is a town guide who explains it very well.

It is well known that lighthouses provide wonderful views and the Ajo lighthouse is no exception to the rule. It is also very strikingly decorated which gives a very special touch to the coastal landscape with the sea in the background.
