Chairs in the Jardin du Luxembourg start the week neatly lined up around the lawns and gravel pathways.  Visitors are free to move the chairs where they wish…..

 

 

with a few exceptions.  Chairs aren’t allowed round the pond, where they’d get in the way of children (or grown ups) sailing model boats.  If you really want a seat by the water you can always perch on the low parapet of the pond.
