Architecture studio Christ & Gantenbein has completed a museum for chocolate brand Lindt alongside its headquarters in the Swiss town of Kilchberg on Lake Zurich.
The museum with a simple red brick exterior to match the surrounding historic factory buildings.
The entrance facade of the cuboid-shaped building, however, is clad in white glazed brick and shaped in a curve to create a focal point and public square.
The museum is arranged around a large,64 metres long, 15 metres high, and 13 metres wide,  atrium that contains the world's largest chocolate fountain, which is nine-metres tall and topped with an over-sized whisk.
Surrounding the atrium a series of spiral staircases, round load-bearing pillars and circular balconies animate the space.
Alongside the atrium on the ground floor will be a reception area, a 500 square-metre shop and a cafe, which also has outdoor seating.
The museum exhibits including an interactive chocolate tour, which were designed by Atelier Brückner, were placed on the floors above.
