The Socoa district, facing the bay on one side and the open sea on the other, is arranged from the Ciboure hill until the dam. It is an exceptional site due its location, its landscape and history, but also because between Biarritz and Hendaye, it is one of the last sites (if not the last) which is still “convertible”. This unique point gives it a certain value. The fort is listed on the Supplementary Inventory of Historic Monuments; the site is subject to an Architectural, Heritage or Landscape Protection Zone (ZPPAUP). This reflects how it is an exceptional site, but this means there are significant requirements in terms of the quality of future developments. It is a complex site made up of several sub-units which follow on from each other, with very different qualities in terms of geography, architectural and landscape shapes and functions. Whilst the specific features require different responses, they should result in a strong, consistent project to reveal, confirm and magnify the quality of the site, and for it to reflect the site’s brand image.
