ECOTRICITY - M4 - JUNCTION 11

At 120 metres tall, Reading's wind turbine is one of the largest land-based windmills in the UK.

Soaring above Junction 11 of the M4, the structure at Green Park has become one of the town's most iconic landmarks.

The turbine was built in 2005 and is owned and operated by Ecotricity, an electricity supplier in the UK that builds wind turbines to supply clean energy to thousands of customers across the country.

It was partially designed by world-famous architect Sir Norman Foster.

Sir Foster is responsible for the egg-shaped nachelle at the top of the structure, which contains its major component.

"It was the early days of the wind industry here in Britain, we'd built quite a few windmills up and down the country already and we were conscious that nine out of ten people at that point had never seen a windmill and there were lots of judgements made in the absence of that. So we thought let's build a windmill in the most visible place we can find right by the M4."
