The Connacht GAA Air Dome at Bekan was inflated yesterday signalling a landmark day in the development of the €3 million facility.
The ambitious structure, which can hold 10,000 people, was inflated over a few hours.
The development at the Connacht GAA Centre of Excellence in Bekan will include state-of-the-art 4G playing surfaces, a running track and a multitude of training facilities.
In recent days a team of engineers have been pulling the inflatable covering over the site. Work on filling it with air began yesterday morning and was completed by early afternoon.
