Tate St Ives has been transformed by a four-year building project.
The gallery reopens on Saturday after work to build a new extension.
The £20m addition has doubled the size of the building and provided space for educational activities and new studios
The extension has been built into the cliff face so it doesn't obstruct sea views.
The gallery will open with a major solo exhibition of sculptor Rebecca Warren, consisting entirely of new or previously unseen works.
This will open alongside a new large-scale display exploring the story of modern art in St Ives.
