MERTON COLLEGE (England), the oldest college in Oxford of its type and all secular colleges later established in Oxford and Cambridge were modeled after it. It was founded by Walter de Merton in 1263 as the House of Scholars of Merton. The endowment consisted of the founder's manor-house and estate at Malden, Surrey, the income going to the MESA VERDE support of scholars at Oxford. Between 1264-74 the scholars were moved from the rented premises to Merton Hall, purchased by the founder. The college buildings have undergone many changes since first established, but the 13th century parts are among the most interesting ing architectural examples in Oxford.
