The north range houses the library and senior common rooms; designed in the Neoclassical style by James Wyatt, it was built between 1788 and 1796 to accommodate the books requested by Edward, Baron Leigh, formerly High Steward of the University and an Orielensis, whose gift had doubled the size of the library. The two-storey building has rusticated arches on the ground floor and a row of Ionic columns above, dividing the façade into seven bays — the ground floor contains the first purpose-built senior common rooms in Oxford, above is the library.
