Different Collections, Different Stories
The simplest way to understand the difference is this. Tate Modern is about international modern and contemporary art. Tate Britain is about British art across five centuries. They are part of the same family of Tate galleries, but their collections, buildings and atmospheres are quite distinct.
Tate Modern opened in 2000 in the converted Bankside Power Station on the South Bank. Its collection spans from around 1900 to the present and includes works by Picasso, Matisse, Rothko, Warhol, Dalí, Monet, Louise Bourgeois and hundreds of other international artists. The focus is on movements and ideas that shaped modern art globally.
Tate Britain sits in a classical Portland stone building on Millbank, near Pimlico. It holds the national collection of British art and covers everything from Tudor portraits through to contemporary installations by living British artists. The Turner collection alone, housed in the Clore Gallery, is one of the most important holdings of any single artist's work in the world.
What You Will Find at Each
At Tate Modern, expect Cubism, Surrealism, Abstract Expressionism, Pop Art, Minimalism and contemporary installation art. The Turbine Hall hosts free large-scale commissions, and the galleries are arranged thematically rather than chronologically.
At Tate Britain, expect the Pre-Raphaelites, Constable landscapes, Gainsborough portraits, William Blake watercolours, Henry Moore sculptures and works by Lucian Freud, David Hockney and Bridget Riley. The annual Turner Prize exhibition, which showcases emerging contemporary artists, has been held at Tate Britain since 2000 (with occasional relocations to other UK cities).
The Buildings
Tate Modern's industrial power station gives it a raw, cavernous quality. The Turbine Hall alone is 152 metres long. The Blavatnik Building extension adds a distinctive angular silhouette to the skyline.
Tate Britain's neoclassical building, designed by Sidney Smith and opened in 1897, has a grand entrance with columns and a rotunda. It feels more traditional and intimate, though recent renovations have modernised the interior galleries.
Location and Getting Between Them
Tate Modern is on the South Bank of the Thames, close to Southwark tube station and directly across the Millennium Bridge from St Paul's Cathedral. Tate Britain is on the north bank at Millbank, closest to Pimlico tube.
The two galleries are connected by the Tate Boat, a river bus service that runs along the Thames between them. The journey takes about 15 minutes and offers good views of the river and the Houses of Parliament.
Which Should You Visit?
If you only have time for one, your choice depends on what you enjoy. Tate Modern is the better pick if you are drawn to big, ambitious contemporary art and the sheer spectacle of the building. Tate Britain is the better pick if you love British painting, want to see Turner and the Pre-Raphaelites, or prefer a quieter, more contemplative gallery experience. Both are free to visit, so there is no financial barrier to visiting both if your schedule allows.
