In writing in a previous chapter of the buildings of Queens' we drew attention to the fact that the general plan of the College followed in the main the lines of a large country house such as Haddon Hall. And in degree this is true of the other college buildings in Cambridge. A mere glance at a ground-plan of Jesus will show at once that the arrangement of the buildings is entirely different from that of any other college at Cambridge, and it is clearly derived from that of a monastery. This accords with what we know of its history. However dilapidated the old nunnery may have become through the poverty and neglect of the nuns, the outward walls of solid clunch, which under a facing of later brick, still testify to the durability of the Nunnery builders, were still practically intact, and Bishop Alcock had too much practical skill as an architect to destroy buildings which he could so easily adapt to the needs of his college, and harmonise to fifteenth century fashions in architecture. In his conversion of the Nunnery buildings to the purposes of his college, Bishop Alcock grouped the buildings he required round the original cloister of the nuns, increasing the size of that cloister by the breadth of the north aisle of the Conventual Church which he pulled down. The hall was placed on the north side, the library on the west. The kitchens and offices were in the angle of the cloister between the hall and library. The master's lodge at the south-west corner was partly constructed out of the altered nave of the church, and partly out of new buildings connecting this south-western corner of the cloister with the gate of entrance. This gateway, approached by a long gravelled path between high walls, known popularly as "the chimney," is one of the most picturesque features of the College. It is usually ascribed to Bishop Alcock, but on architectural evidence only. It is thus described by Professor Willis:-- "The picturesque red-brick gateway tower of Jesus College (1497), although destitute of angle-turrets, is yet distinguished from the ground upwards by a slight relief, by stone quoins, and by having its string courses designedly placed at different levels from those of the chambers on each side of it. The general disposition of the ornamentation of its arch and of the wall above it furnished the model for the more elaborate gate-houses at Christ's College and St. John's College. The ogee hood-mould rises upwards, and the stem of its finial terminates under the base of a handsome tabernacle which occupies the centre of the upper stage, with a window on each side of it. Each of the spandrel spaces contains a shield, and a larger shield is to be found in the triangular field between the hood-mould and the arch." Professor Willis thus describes also the Conventual Church and the changes which were made by the Bishop in his conversion of it into a college chapel.
