Here's some shots of the artwork on the Montreal subway (or the metro as it's known). First off are a couple from a large stained class piece at Place des Arts metro station. As the name implies, it located amidst some of the major performance venues in Montreal.
This particular piece shows various Canadian and Quebecois composers. Lenses used: 02 zoom for first two, 03 fisheye for the third.
Here is another one at Berri-UQAM metro station, also stained glass. It depicts some of the people who founded Montreal.
Although I lived in Montreal for several years, I never paid much mind to the art on the subways until I moved away. C'est la vie, n'est pas? The type of artwork you see on the metro varies in style, subject matter and how it is integrated into the station. Sometimes, it is an obvious piece of art, other times, it is more subtle, like an artistic flourish. It is said to be one of the foremost subway systems with respect to the amount of art and also the quality and how well integrated the art is.
