Every week, thousands of people take the industrial staircase at the 5445 and 5455 de Gaspé, in the Mile End. They spend in total tens of thousands of minutes in transition between a space and another, moving between white walls with changing numbers. We want to build bridges in unusual spaces and gather the community around what makes us think and dream. It's time for urban art to take its place in the heart of the buildings, at a human scale. After Barcelone, Amsterdam, Berlin and St-Petersburg, Montreal have its own street art museum. In total, 24 murals created by 24 montreal artists made an unusual space shine...the industrial stairwell!
