The National Portrait Gallery

• This was the very first portrait gallery in the world when it opened in 1856, and to this day is still one of the largest — there are almost 200,000 portraits here! Open daily from 10am-5pm (10am-8pm on Thursday and Friday).
• The Tate Britain – Not to be confused to with the Tate Modern, the Tate Britain is a gorgeous museum home to an expansive collection of British artwork from the 16th century to the present. It’s not as big as the Modern, but it arguably has more famous works of art, including works by Francis Bacon, Richard Dadd, and William Blake. Open daily from 10am-6pm.
