It is the home of the Large Hadron Collider, and the birthplace of the World Wide Web.
And for a number of Ulster businesses, the CERN laboratory in Geneva could also be a source of lucrative and prestigious contracts.
That is according to Invest NI, which hosted an event calling on Northern Irish companies to compete for business at the lab.
Hosted in conjunction with the Science & Technology Facilities Council, it took place last Wednesday.
CERN, which is an ackronym for the European Organisation for Nuclear Research, is the largest particle physics laboratory in the world.
It has an annual procurement budget of about £200m, of which just over a tenth is spend with UK companies.
Representatives from 28 companies attended the business breakfast to learn more about the types of contracts that are available.
Invest NI said’s Kevin McCann said: “Last year UK companies secured in the region of £22 million worth of contracts from CERN so we are keen to make sure that Northern Ireland businesses take full advantage of the supply opportunities on offer.
“The main purchasing areas are in advanced technology, electrical engineering, electronics, computer systems, vacuum and low temperature technology and particle detectors.”
Contracts are also available in fields such as mechanical structures, civil engineering, and support services.
In 2009 Elite Electronics in Enniskillen, secured a contract to provide electronic units for use at the core of the accelerator, and has continued this for five years.
