The powerful message behind strange signs that have appeared in Cardiff

People in Cardiff may have spotted some unusual signs in the city centre recently. On Wood Street, near the Principality Stadium, there are two construction signs - one that notes 'Caution Suicide in Construction', while another says 'Diversion The Lost City'.

But these signs carry a powerful message behind them. They are connected to Project 7000: The Lost City campaign, which aims to raise awareness of the 7,000 construction workers who have died by suicide in the last decade in the UK. For the latest Cardiff news, sign up to our newsletter here.

According to the project, the figure is a "crisis" but one that it is "unknown" outside the industry. On their website, their campaign reads: "This is the city that will never be built. Because the 7,000 construction workers it would take to build it have died by suicide in the last decade.

"The construction industry has a suicide rate four times the national average. It's a crisis, but one that's relatively unknown outside the industry. By visualising exactly what they could have built, The Lost City addresses this crisis, showing the true scale of construction suicides. This is the city that could exist if the construction suicide crisis didn't."

To launch their campaign, 7,000 hard hats will be placed across the UK in 10 cities, each representing a life lost to suicide within the construction industry. London, Bristol, Cardiff, Birmingham, Nottingham, Manchester, Liverpool, Leeds, Newcastle and Edinburgh will see reimagined construction signs, which aim to serve as poignant reminders of the workers who could have built homes, schools, and hospitals but were lost to mental health struggles.

According to On The Tools, a construction news service, 26% of tradespeople are more likely than workers in other industries to experience mental ill health in the UK. On The Tools has created a report which aims to explore the true state of mental ill health among UK tradespeople and campaign for changes to be made.

In response, Project 7000: The Lost City has vowed to raise money to help the cause, which you can find out more here. According to the project, their objective is to raise £2.5million for therapy sessions to save the next 7,000 construction worker.
