The Tulip Stairs
Looking up the Tulip staircase.
The elegant Tulip Stairs in the Queen's House are the first geometric self-supporting spiral stair in Britain. Although called the 'tulip' stairs, it is thought that the stylized flowers in the wrought-iron balustrade are actually fleurs-de-lis, as this was the emblem of the Bourbon family of which Queen Henrietta Maria (wife of Charles I) was a member.
