Tented love: how Senegal created a spectacular new African architecture

After independence in 1960, the country cast off western influences and forged a new African style full of triangular forms, rocket-shaped obelisks and rammed earth. Is this spirit now being suffocated? Our writer takes a tour of the capital

Visiting the International Fair of Dakar is like taking a stroll through the ruins of some ancient Toblerone-worshipping civilisation. A cluster of triangular pavilions rises from a podium, each clad in a rich pattern of seashells and pebbles. These are reached by triangular steps that lead past triangular plant pots to momentous triangular entranceways. All around, great hangar-like sheds extend into the distance, ventilated by triangular windows and topped with serrated triangular roofs. All that's missing is triangular honey from triangular bees.
