University College London
Founded by admirers of Jeremy Bentham (not, as is often thought, by Bentham himself), University College has a reputation for being one of the more liberal colleges. It offers a balance in its departments and courses between arts / humanities, and science. As such it tends to attract a 50%/50% male to female ratio.
Of note besides medicine, UCL has a theatre The UCL Bloomsbury Theatre, a faculty of law, a school of architecture ([The Bartlett]?), good medical and life sciences departments and a renowned physics and astronomy department.
