Clos Montmartre, Paris' only working vineyard. Production is limited and proceeds benefit charity. The Fête des Vendanges, in early October might be a fun festival to put on your list if you happen to be in Paris in October. I've photographed this lovely little vineyard several times but only by pushing my lens through the fence. I am not sure if it's ever open to the public.
I'm pleased to offer my newest calendar: Blanc et Noir en Paris 2011 through Red Bubble! Of course if you want a color Paris calendar, just look on the sidebar at la Boutique!
