Flowers bloom near one of Doha's future metro stations Labourers work on a large flower arch installation, made up of 7.400 flower pots, near a future metro station on the Doha Metro Red Line in Doha's city centre, which is set to partially open to the public on May 8. The arch is meant to provide shade to future commuters walking from the Corniche or the main Post office building to the metro station. IMAGES
