Overlooking the Atlantic far from the bustle of London, the Tate St. Ives at Porthmeor Beach in Cornwall is in the midst of wrapping up a four-year, £20 million (about $25 million) project that will be complete this fall. Reopening Oct. 14, with double the original space for galleries and learning activities, the new space will be open year-round and boasts a column-free area naturally lit by six enormous skylights. The design is by award-winning Jamie Fobert Architects, and includes a public rooftop garden and handmade ceramic tiles in hues of blue-green that reflect the sky above and the sea below the cliffs.

“The level of ambition shown in the new Tate St Ives is extraordinary,” says Kerstin Mogull, managing director, Tate. “On the side of a cliff surrounded by a beautiful historic town, we are managing to double the size of the galleries, double the space for learning activities, and even increase the amount of outdoor public space. I’m sure the results will amaze our visitors when we welcome them this October.”

The opening will be celebrated with a major retrospective of works by sculptor Rebecca Warren. Other exhibitions include British and international artists Ben Nicholson, Peter Lanyon, Barbara Hepworth, Piet Mondrian, Naum Gabo and Paule Vezelay. Seasonal exhibitions will be hosted in the new galleries, with upcoming events including a 2018 exhibition of women artists inspired by Virginia Woolf, painter Patrick Heron and a project commissioned by contemporary artists Rosalind Nashashibi and Lucy Skaer. How to get there? Regular rail service between London Paddington and St. Ives is available via the National Rail system.
