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. It was completed only in 1638—just before the Civil Wars cut both Charles and his building schemes off at the head, and Henrietta scurried off to France. The house has a few pleasant galleries and displays, including Orazio Gentileschi’s Joseph and Potiphar’s Wife, which, after the house’s 2016 restoration, was returned to these walls for the first time since around 1650. The nautilus-shaped Tulip staircase, plus other rooms, are considered to be haunted by an unknown specter, so have a camera ready.
