Arena das Dunas

Location: Natal, Brazil
Capacity: 42,000

Located in Natal, on Brazil's north-east coast, the Arena das Dunas hosted four group matches during this summer's World Cup.

Delivered on time and under budget, its design is inspired by the region's undulating sand dunes – dunas in Portuguese. The stadium's design also ensures an abundance of ventilation and natural light.

The stadium has been hailed as one of the "greenest" arenas of the World Cup, with a roof designed to store and re-use rainwater.

According to Populous, the architects that designed the stadium, "up to 3,000 cubic meters [of rainwater] may be captured and reused in the lavatories and for irrigating the pitch."
