A website has also been created giving more details of the event and also the opportunity to win a prize beforehand. A riddle will be placed on the site, and the first person to solve it and send the correct answer will win a night in a top hotel in Paris on the night before the event (Friday 3rd of July). Good luck!
This event has been organised by a very interesting agency called ‘Ma langue au chat’, specialists in treasure hunts and other similar events. Look out for a feature on them on Invisible Paris very soon!
