This extraordinary diner is the final wonder of the great Brazilian architect Oscar Niemeyer, who dreamt it up at the age of 103. And it’s a fine place for a sunset kombucha and gin

Perched among old brick buildings in an industrial neighbourhood of Leipzig in eastern Germany, a giant white sphere appears to hover over the corner of a former boiler house. Is it a giant’s golf ball? An alien spacecraft? A fallen planet?

Twelve metres in diameter, the Niemeyer Sphere is the final design of world-famous Brazilian architect Oscar Niemeyer and probably the most surprising creation by a visionary who valued the sensation of newness in art above all else, the result being mesmerising buildings that seem both space age and out of this world. The Sphere is like a vision from the future, dropped among used-car dealerships and construction equipment rental outlets, in a working-class neighbourhood that few tourists would ever pass through by design.
