Buried art treasures at Tate St Ives in Cornwall
A new £20m extension to the Tate St Ives art gallery in Cornwall has been unveiled.
The extension creates nearly 600 sq m (6,460 sq ft) of extra space.
It has been built into the cliff face after local objectors said the scheme would block views of the sea and take up car parking space.
The extra space will allow the gallery to remain open all year instead of closing while exhibitions are changed.
