“I remember the sound of the horns from the great ships that sailed the Clyde, also the sound of the horns in the ship yards telling me that my Dad would be home soon…”

That quote comes from a Glasgow discussion forum on the city sounds you no longer hear. No more evocative hooters, fog horns, hammering and drilling, marking the time of day and changing weather.

Heavy industry has given way to the quieter construction of digital technology. But with Glasgow combining commerce and science in new creative businesses, the term Clydebuilt takes on new meaning.

And there are tributes to the past. The titanium-clad crescent-shaped structure of the Science Mall resembles the canted hull of a ship in deference to the nearby Canting Basin where boats were loaded and unloaded.
