Somerset House is a major arts and culture center in the heart of London overlooking the River Thames, just east of the Waterloo Bridge. Somerset House features large-scale contemporary exhibitions, galleries, events, two elegant staircases and balcony views over the Thames. The famous courtyard and vast Georgian building provide a beautiful backdrop for 55 dancing fountains in the summer and an ice rink during the winter months. Open between 10am and 6pml every day, most galleries are free, as are guided tours every Thursday and Saturday.
Some exhibitions, like the recent Valentino: Master of Couture, will set you back about £13 and it is advised you book ahead.
