The existing Chapel was built by yet another Bishop of Ely closely connected with the College, Dr. Matthew Wren, Master here 1625-1634. He was uncle to the great Sir Christopher Wren, the architect of St. Paul's, and had enough architectural originality of his own to aim at copying the beautiful tracery of the mediaeval church-builders. It was the first time that any such attempt had been made in England; and this going behind the Reformation roused the Protestant feeling of the time to fury. Men declared it incredible that there could be "so much Popery in so small a chapel"; and when the Civil War gave the Puritans their opportunity Wren paid for being so far in advance of his age by an imprisonment of not less than eighteen years, till released, in 1660, by the Restoration. The Chapel windows are now filled with some fine Munich glass, the only example of this work in Cambridge. Besides the Chapel, the Library here is remarkable, and the "Combination Room" boasts itself as almost, if not quite, the finest apartment of its kind in all Cambridge. This name, we may mention, is given in every College to the parlour whither the M.A.'s retire, after dining in Hall, for wine, dessert, and conversation.[6] That of Peterhouse is a luxurious apartment, panelled with oak, and with stained-glass windows. [Footnote 6: The corresponding Oxford name is "Common Room."] Another feature of the College is its little deer park, the only one in Cambridge, and, with the exception of Magdalen College, Oxford, the only one in either University. Access to this is obtained by passing through the passage between the Hall and the Kitchen. Beyond the deer park again an iron gate leads to the College Gardens, the only College Gardens in Cambridge which visitors may freely enter. And they are well worth entering. There is, however, no way through this College, as there is through many, and we must leave it through the same gate as we entered by, thus returning to the street. Over the gate we observe the coat of arms belonging to the College, the armorial bearings of the founder surrounded by a border of crowns. This feature will be seen in every College, for each has its own arms, and these are invariably emblazoned above the entrance. [Illustration: _St. Mary the Less, South side._]
