According to Nikolaus Pevsner, Lincoln College preserves "more of the character of a 15th century college than any other in Oxford". This is mainly because both the facade to Turl Street and the front quad are still of only two storeys (although the parapets and battlements are of the 19th century). The College also owns most of the buildings across Turl Street from the college proper, in whole or in part, which chiefly contain student accommodation. The creeper that covers the College's front quad walls is Virginia creeper ("Parthenocissus quinquefolia"), dark green in the summer, through to scarlet in autumn, whilst being bare in winter.
