Viewed from the river and framed by the newer Old Royal Naval College, the Queen’s House enjoys as elegant a setting as a building could wish for. Inigo Jones took 22 years to come up with a then-revolutionary, Palladian-style summer retreat for Charles I’s wife, Henrietta Maria, but it was completed only in 1638, just before the Civil Wars cut both Charles and his building schemes off at the head. Henrietta scurried off to France. The house has a few ho-hum galleries and displays (lots of paintings of ships and battles), but its nautilus-shaped Tulip staircase, plus other rooms, are considered to be haunted by an unknown specter, so have a camera ready.
