Kirkaldy’s Testing Works in Southwark is to Materials Testing what Greenwich is to Time.
“Treat your inner engineer, go visit!"
We welcome everyone to this authentic, historic innovation space in the heart of London’s Bankside, to celebrate how science and design can solve engineering’s challenges. And get hands on with historic working machines. Go on, break something.
Carved above the door is David Kirkaldy’s declaration ‘Facts not Opinions’. Inside, his 116 ton Universal Testing Machine, which set world standards for engineering, still breaks metal today. Come and see for yourself!
“Our visit was brought to life by your wonderful volunteers…What a stimulating time, and an amazing space. A huge thank you to you all!” The Bompas & Parr team

Find out about our next open days:
On 1 January 1874 Scottish engineer David Kirkaldy opened the world’s first purpose-built, independent commercial materials testing house at 99 Southwark Street London. Inside, his patented 116-ton hydraulic-powered Universal Testing Machine could exert a force of up to 1,000,000lb, bringing rigorous new understanding to the strength of construction materials. Outside, he declared his independence over the door, ‘Facts Not Opinions’. The machine, and his challenge, are still here today.
Machines in action, not glass cases.
After three generations, and close to 100 years in business, Kirkaldy’s Testing Works has a new mission. Volunteers now open the unique, atmospheric workshop with its still-working Universal Testing Machine to visitors, engineers, artists – everyone who wants to discover and bring new life to this remarkable place, which changed the way we built our world.
