Founded in 2009 by Derek Lamberton, Blue Crow Media is an independent publisher dedicated to creating thoughtfully designed and carefully curated city maps. Our publications began with a series of food and drink city maps and apps, and since 2015 we have published a series architecture and design guide maps. The New York Times describes the maps as "part design manifesto, part urban architecture guide".

The majority of our maps celebrate Brutalist and concrete architecture, from London to Tokyo. We also publish an annual calendar dedicated to Brutalist architecture.
