There are a few interesting events in Paris this weekend which has inspired me to list them here. It must be the return of Spring.
La Nuit de la Chouette (Owl Night)
A Chance to track down a few owls in parks and forests around France, in the company of experts. Nothing in Paris, but there are a few events in the surrounding departments.
Saturday 23rd, http://nuitdelachouette.lpo.fr/
Focus on the nightlife of this (in)famous part of the city over three days. Perhaps most interesting of all are the parcours nocturnes, or alternative guided tours through landmarks of prostitution and gang warfare!
Salons des vins des Vignerons Indépendants
The bi-annual independant wine producers' fair.
The 303rd Metro Station
At 12pm on Saturday, the first train will leave Mairie de Montrouge on the Line 4, the 303rd Metro station in Paris. To accompany the event, a whole series of activities are planned.
