This college was built by the Jesuits who planted a vine here brought back from Palestine. Three centuries later this tree still bears fruit and is harvested annually. Inside, admire the refectory decorated with wood panelling and paintings retracing the lives of Ignacio de Loyola and François-Xavier; the library, with its Baroque wood decoration; and the underground section, which includes a 17C cellar and medieval and Gallo-Roman galleries.
