Urtubie Castle is a private manor house that has belonged to the same family since its construction began in 1341. Its current owner, Laurent de Coral, represents the 24th generation to live and maintain it. It is located in the commune of Urrugne, 3 km from Saint Jean de Luz. Its very ancient history is that of a family, but also that of the Basque Country and that of France.

This is the peak of a small mountain below the castle of San Markos and where the castle of Kutarro once stood. Now the castle is in ruins, but there are picnic tables and it is a good area to visit.
