Musée Matisse in Nice

You're standing in Cimiez, the hilltop neighbourhood above central Nice, in front of the Musée Matisse. The museum lives in a villa that's far older than the art inside it. Take a good look at the façade. It's painted a warm red ochre, and some of the windows aren't real at all: they're painted onto the wall. That trompe-l'oeil trick is typical of the Genoese style this villa was built in.
