Security openings in the walls of the Royal Opera of Versailles at the 1961 Kennedy reception
Watching newsreel footage of the Kennedys' state visit to France in 1961, I noticed some curious openings in the wall of the Royal Opera of Versailles. What are these little squares, scattered across the different tiers of the auditorium, for?
They are neither heating nor lighting vents. They are security windows.
The Opera was guarded on all sides. Special men, known as mouches, kept watch in the niches behind these little windows, armed with firearms. The placement of the niches along the circular entablature of the columns gives a complete view of the auditorium, so that any likely danger might be eliminated.
The Kennedys stand beside General de Gaulle, with Yvonne de Gaulle to the right of the President. That day the entire upper crust of French society had gathered at Versailles; in the photograph one can make out, for instance, Hubert de Givenchy
