A THREE-day birthday bash is taking place on top of one of the Clyde's tallest structures.

Distillery bosses at Whyte & Mackay have transformed part of Clydebank's Titan Crane into a cosy pub, which will offer patrons a wee whisky or two along with spectacular views.

The Glasgow-based distillery opened the world's first pub on top of a crane to celebrate its 170 anniversary.

The historic crane's wheelhouse has been kitted out with fake brick walls and cosy bar stools to form a makeshift pub 150 feet up in the air at the top of the Clydebank landmark.

The pub, which will give each patron two free drams, has been named The Lion's Clyde.

Global marketing director Steven Pearson said: "We're very proud of our Clydebuilt roots.

"The Lion's Clyde is about celebrating the past but also the present by bringing people together to enjoy a dram at their local.

"The Titan is an iconic part of the Clyde's history and we're absolutely delighted to work with them on this unique project."

The crane is more than 100-years-old and played a pivotal role at the John Brown shipyard, where it was used to help build the three Queens - the 20th century landmark liners Queen Mary, Queen Elizabeth and Queen Elizabeth 2.

The Titan Crane - a historic Category "A" listed structure - underwent a multi-million pound makeover when it was transformed into a tourist attraction seven years ago.

Alan Robertson, projects director at Clydebank Re-built said: "We are delighted to welcome this week Whyte & Mackay to the Titan Crane, Scotland's unique visitor attraction.

"It is an opportunity to celebrate with a dram the founding of Whyte & Mackay 170 years ago on the Clyde. Where better than at the top of the Titan, a great icon of Scotland's shipbuilding and engineering heritage?"
