With wide foresight, we visited Maisons La Roche et Jeanneret when we made a  trip to Paris in 2008. We only visited it from outside though, and If I remember correctly it was under renovation as well. So not really a tick-off.

In February 2022 we went to Marseille by train. Due to storms in Germany we arrived 2 days late. So had only half a day to see Marseille. Right after breakfast we took the metro and bus to Cité Radieuse. At first glimpse it looks like our Corbusier Haus in Berlin built for IBA 1957. But it has a few more details. We visited the floors which are accessible. Looks like nothing changed here since the 50th, thus it didnt loose any of this eras charme. Finally we went onto the roof. Amazing view at the Calanques and above Marseille.I still plan to visit further components. But this one is definitely top-notch.
