University College Lonon (UCL) is the oldest multi-faculty constituent college of the University of London, and is one of the university's two original founding colleges. It is also the first British University to have been founded on a secular basis, and the first to admit students regardless of race, class, religion or gender. With over 25,000 staff and students, UCL is the largest college of the University of London, and is larger than most other universities in the United Kingdom. It is a member of the elite Russell Group of Universities, a part of the 'G5' sub-group of super-elite UK universities, and a part of the Golden Triangle.
