Oxford’s legendary members’ society is famous for its feisty debates, prominent international speakers and marvellous Pre-Raphaelite murals, painted between 1857 and 1859 by Dante Gabriel Rossetti, William Morris and Edward Burne-Jones. Although most of the building is off-limits to nonmembers, you can visit the library to see the murals. They depict scenes from the Arthurian legends, such as Arthur’s first victory with the sword, but can be tricky to see on bright days, as they surround the flower-shaped windows.
