A glimpse through an interstice caught. . .*
Looking out through leaded glass windows.
The Musée de Cluny or National Museum of the Middle Ages is a wonderful small museum in the Latin Quarter of Paris — and the home of “the Lady and the Unicorn” tapestries.
Unfortunately, this was the closest look that I could get of its modern take on a medieval garden — designed by Eric Ossart and Arnaud Maurieères. It was closed for “security reasons” the first week of September. Since it opened in 2000, I suspect that the wooden decking needs repair or replacement.
Travel tip: admission to many Paris museums is free on the first Sunday of each month — many more will be free starting in November.

That’s going to be on my list when in Paris. I love gardens in museums. Thanks!
I hope the garden will reopen soon. — Maybe by next spring. The museum interior is great though.
Just an update (from May 2016): the garden is still closed for “security reasons,” although, looking through the fence, they have kept up the plantings. The museum is doing a lot of work on the attached Roman baths, and, maybe, they plan to reopen the garden when it is finished.
