The essential accessory to all the best “archi-travel” this year? The city map Modernist Belgrade by Blue Crow Media, it turns out. Founded by former National Geographic journalist Derek Lamberton, the indie publisher has released a series of two-sided guides to the world’s most unsung architecture. Or, to some, its ugliest. It depends whether you consider the stark Brutalist buildings of cities like London or Sydney “eyesores or icons”, he says. Clearly he’s a fan, but so are a growing number of urban adventurers: Brutalist London is one of his bestsellers. Still, the series is not just limited to Europe’s big capitals. One of the best cities for scoping out obscure, mid-century city-scapery is Belgrade (pictured). “It’s so different; Novi Beograd (“New Belgrade”) was built from nothing on a swamp after World War II. The architecture is viewed very differently, depending on people’s age, financial situation and so on.” Even so, architecturally, “it’s truly remarkable”, he says. Just don’t expect the Taj Mahal.
