REHEARSALS have taken place on Liverpool's waterfront tonight for what promises to be a spectacular art and light show forming part of the celebrations for this weekend's visit to the city by Cunard liners The Three Queens.

The iconic Liver, Cunard and Port of Liverpool Buildings will become the canvas for the state-of-the-art 3D Amazing Graces art projection.

Described as a '30-minute visual feast' by its producer, the Colour Project, the show will be beamed onto the historic buildings at 10pm on Saturday, Sunday and Bank Holiday Monday.

Without giving too much away, it is a stunning show.

It explores the spirit of Liverpool and is a celebration of the city's culture and heritage along with its Cunard links.

Claire McColgan, head of culture for Liverpool City Council told the Globe tonight: "It's a fantastic weekend for the whole region.

"It's been a brilliant experience working with colleagues across the water and over in Sefton. It's going to be a great weekend for the whole region.

"The projection show is just amazing; people won't have seen anything quite like it before.

"It tells the story of Liverpool, tells the story of Cunard, tells the story of the whole renaissance of this city and its relationship with its maritime heritage. It!s just brilliant.

"It's about 25 minutes long and you've just got to see it."

It's all part of a weekend of celebrations for Monday's visit to the River Mersey by The Queen Mary 2, Queen Elizabeth and Queen Victoria, in celebration of Cunard's 175th anniversary.

The projection also includes a Sea of Faces which will see 175 faces of Liverpool people projected on to the buildings. The 175 people selected were chosen from more than 700 submissions.

The Three Queens will meet for the first time in an event that will make maritime history and will commemorate the first transatlantic sailing from Liverpool – 175 years on.

Almost one million people are expected to watch the ships when they arrive on Bank Holiday Monday.

Looking forward to the weekend's events, Claire McColgan continued: "We've got different things happening on the pier head though out the weekend.

"The big challenge for us, we're going to have thousands of people on the pier head to see the ships was that we couldn't clog up it with stages like we'd normally do. 

"So, we've got lots of water features going on, lots of street buskers and a concert.

"It!s nerve-wracking, but going to be an exciting weekend."
