Scotland's tallest free-standing building is to reopen after being closed for almost 18 months.
Glasgow Tower has been closed longer than it has been open
The 416ft (127m) high Glasgow Tower will welcome visitors on Thursday.
The £9m tower has been shut since August last year after a series of glitches were identified. Bosses said small problems had been fixed.
Kirk Ramsay, Science Centre chief executive, said: "We are thrilled to be reopening the tower and we look forward to extending a warm welcome."
The tower, which forms part of the Glasgow Science Centre complex in Govan, was opened in a blaze of publicity in 2001.
It has been shut longer than it has been open due to a series of problems.
The tower was shut down within five months after a major structural fault was discovered, remaining closed for the next two-and-a-half years.
And it had to close for another five months from January 2005 after visitors got trapped in a lift.
VisitScotland's chief executive Philip Riddle welcomed the tower back on to the tourist trail.
He said: "As one of Glasgow's most popular visitor attractions, and well deserving its five-star status, we are delighted to hear that the tower will reopen in time for Christmas."
