The centre has pledged to work as quickly as possible with Glasgow Council to restrict the closure to one week.

The centre said the full public opening of the Millennium Project building was now being delayed until next Thursday.

Spokesman David Grimmer said: "The full public opening of the Science Mall, the main exhibits building at GSC (Glasgow Science Centre), has been delayed.

"Although GSC has fulfilled the requirements of building control, environmental health, and the firemaster, the granting of a full public entertainment licence is still awaited.

"Although GSC and Glasgow City Council are working together to resolve the issue it will not be possible to admit the paying public until after Thursday June 28."

The Imax Theatre, the first phase of the complex which opened last October, continues to operate as normal, GSC officials said.

The royal opening on July 5 by the Queen is not affected.

The Science Mall is the centrepiece attraction of the centre which is expected to receive up to 600,000 visitors a year.

Creativity and innovation

The four floors of the mall house hundreds of interactive exhibits made up of light beams, mirrors, optical illusions, audio and computer displays, and water tanks.

Among its attractions is Britain's first publicly accessible virtual reality theatre, Scotland's biggest planetarium and solar sunflowers.

The three floors above ground level focus on the themes of exploration and discovery; creativity and innovation and issues and impacts.

The mall and the Imax theatre are the first titanium-clad buildings in the UK.
