That the Parisian underground includes one of the most spectacular tunnel systems throughout Europe is general knowledge not only since the renowned National Geographic published a nice photo gallery of the catacombs.
Now, after their phenomenal New York project with 100 artists mounting an unsanctioned show in abandoned tunnels during a one-year period, also the Underbelly team around Pac and Workhorse discovered the deep paths worming under the French capital and brought some of the most creative heads - including C215, Futura, Conor Harrington, How and Nosm, Saber, and SheOne - to create the Underbelly Project Paris!
