Construction work has begun on the new £74m transport museum on the banks of the River Clyde in Glasgow.
The city's Lord Provost, Bob Winter, cut the first turf at the Riverside Museum site on Tuesday morning.
It has been hailed as the biggest museum project in Britain and when completed in 2011 will house about 3,000 objects.
Earlier this year, a campaign was launched to raise £5m of public money to help fund the iconic development.
Money for the move from Kelvingrove to the Clyde will come from the city council, the Heritage Lottery Fund (HLF) and Glasgow Harbour.
Dr Sheena Wurthmann, a member of the HLF's Committee for Scotland, said: "Today we have witnessed an exciting milestone in the redevelopment of Glasgow's riverside.
"This project will not only allow the Museum of Transport to engage people in their past in a more interesting and dynamic way, but it will be a stunning tourist attraction, bringing life back to this area of the city."
The building has been designed by internationally renowned architect, Zaha Hadid.
She said: "I am delighted that construction on the museum is starting. It's a moment of excitement and expectation for all of us working on the project and for the city of Glasgow.
"I see the museum as a place for people of all ages, reflecting the importance of Glasgow's significant contribution to worldwide commerce and communication, whilst feeding the cultural vitality of the city and inspiring new generations to innovation."
