Boulby Underground Laboratory is the UK's deep underground science laboratory located 1.1km below ground in Boulby Mine, a working polyhalite and salt mine in the North East of England.

Boulby is one of just a select few facilities in the world suitable for hosting ultra-low background and deep underground science projects. It is a special place for science, 'a quiet place in the Universe', where studies can be carried out almost entirely free of interference from natural background radiation. It also provides access & support for studies of the geologically interesting deep underground environment.

​Science at Boulby ranges from Particle Physics and Ultra-Low Background science, Earth and Environmental science, Biology / Astrobiology, Planetary Exploration Technology Development and more. ​
