On a recent visit to Grenoble, I discovered a hidden Art Deco gem, le Garage Hélicoïdal. It is practically invisible from the street, squeezed between other buildings.
Louis Fumet and Louis Noiray, the local architects designed it in the late 20s, and it was completed in 1932. It originally offered extra services to the drivers, repairs, car-wash, petrol station, and a concierge.
I made my way to the top, discovering an amazing view to the Alps. Those who have garages on the roof surely start their day with a smile, as they drive down the 7 revolutions of the concrete ramp to the street!
