Pembroke has a level of academic performance among the highest of all the Cambridge colleges; in 2013, 2014, 2016, and 2018 Pembroke was placed second in the Tompkins Table. Pembroke contains the first chapel designed by Sir Christopher Wren and is one of only six Cambridge colleges to have educated a British prime minister, in Pembroke's case William Pitt the Younger. The college library, with a Victorian neo-gothic clock tower, has an original copy of the first encyclopaedia to contain printed diagrams.
