HISTORY detectives are being urged to join a heritage trail with a difference in honour of Greenock's most famous son James Watt.

Rig Arts' new Watt? heritage project includes an augmented reality trail, stunning Watt sculpture, a new comic book, play and animation.

The celebration combines traditional aspects with modern technology and the Rig team worked with St Patrick's Primary, St Columba's High, Inverclyde Shed and the local Tourist Group on it.

Karen Orr, of Rig Arts, says she is delighted with the end result of a project which she hopes will appeal to all ages and attract visitors to the town as well as local people.

She said: "I am really proud of this.

"I feel it's one of the best heritage projects we've ever done.

"The augmented reality app is also a platform we can build on and add to."

The centrepiece of the trail is her husband Jason's striking James Watt sculpture, Breaking the Mould.

It has pride of place in the gardens of Greenock's Watt Institution and has been a real labour of love for the artist, who specialises in fine art, sculpture, film and photography.

Karen said: "He based the sculpture on 3D scans of the Francis Chantrey bust."

The Watt trail starts on William Street with two interactive plaques, then moves on to the Watt Institution before another stop at the Watt Cairn at Greenock Cemetery.

People can download a free app to their phone and then simply point their mobile at the plaques on the trail to find out more.

The bust of James Watt comes to life and talks about his inventions - which are also illustrated on the app - and gives a summary of his career.

Karen said: "The other plaque at the Watt Institution also refers to the fact that James Watt's dad was a merchant ship owner who benefited from the slave trade.

"James Watt cancelled an order of engines after a slave revolt in the French colony of San Domingo 1791.

"He said slavery was a disgrace to humanity.

"We've always referred to the slavery connection, as you have to show the good and the bad.

"He did benefit from his dad's wealth and he also took a stand against it."
