A rotating viewing tower at a visitor attraction is to re-open to the public this month after almost four years.
The 127m (417ft) Glasgow Science Centre Tower has been beset by technical problems since it opened in 2001 and has remained shut since September 2010.

It will re-open on Saturday July 19 after a £1.8 million refurbishment, including new lifts.
Operators said experts familiar with the structure have worked with the Glasgow Science Centre to rectify "long-standing issues", and the revamped Tower offers an enhanced visitor experience.
An interactive "timeline tunnel" and map will give visitors the opportunity to learn about the history of Glasgow and the Tower site. They can also use a virtual panoramic view to zoom into more than a dozen places of interest.
The £9 million tower holds the Guinness World Record for the tallest, fully rotating free-standing structure in the world and on a clear day offers panoramic views of up to 20 miles.
It had been open a number of months when it emerged in February 2002 that a base bearing had failed and it was sinking into the ground.
Three years later, 10 people became trapped in the lift halfway up the tower when a cable snapped.
Stephen Breslin, chief executive of the Glasgow Science Centre, said: "We are excited to return Glasgow Tower back to the city this summer. It is an iconic landmark along the River Clyde and a world-class feat of engineering.
"We have been working on bringing the Tower back into operation for some time now and we are pleased that it will be open for visitors from both at home and abroad to enjoy this summer.
"There has been a significant investment in the refurbishments and the visitor experience to ensure Glasgow Tower is a must-visit location for Glaswegians, Scots and international visitors alike."
The Tower, which will cost £4.95 to visit, will remain open for the rest of Glasgow Science Centre's summer season before closing on November 2 for the winter.
