I think they would be fine using CERN, If it's aesthetically more pleasing than longer name. We also have Oracle (rather than Temple of Apollo or something).
EDIT: Or wait, is the building actually called Oracle?

looks like it is
Not exactly. There was no building or structure called the Oracle in classical Greece. There was the Panhellenic Sanctuary at Delphi, which was known as the
Omphalos, or Navel of the Earth. There were several temples there, but the important one for us was the Temple of Apollo, or
Apollonion, in which the Pythia, or Oracular Priestess was located.
So, 'Oracle' referred to a person, not a building, although in her favor the Pythian Oracle was one of the most powerful women in the Greek world.
There were five temples to Apollo on the site, but the first three are Mythical, built by the Gods of weeds, feathers, wax, or Bronze. The fourth temple was stone but was destroyed in 548 BCE, replaced by the 'Fifth Temple' which is the one famous as the home of the Oracle. Unfortunately, while there are several descriptions of the exterior and some surviving columns and foundation of the building, here are none of the entire interior since part of it was a Sacred Site off limits to visitors. Various novelists over the years have tried to reconstruct the proceedings and physical surroundings of an oracular visit, but none of them agree.
