An Urban Maze - a podcast by BBC World Service

Some parts of towns are hard to navigate and seem like an urban maze. Navigation expert Dr Ruth Dalton explains to Jordan Dunbar that it’s to do with “intelligibility”, as they go on a tour of the Barbican Estate in London, a famous example of Brutalist architecture, which people struggle to find their way around. The technique for finding your way out of a maze is also revealed.
