The entrance generally used is the North Porch, known as Solomon's Porch. It was erected in the reign of Richard II., but entirely changed its character in the hands of Wren, who appears not to have appreciated the beauties of Gothic architecture. The same architect is said to have built the two western towers, though they are sometimes ascribed to his pupil Hawksmoor. Wren's work upon the north porch was again altered by Sir G. G. Scott, who introduced the present triple portico. On passing under it we come to the north transept, generally known as the Statesmen's Aisle. Here in the same grave lie the Earl of Chatham and his famous son, William Pitt. Close to them are either the graves or monuments of Fox, Castlereagh, Grattan, Palmerston, Peel, the three Cannings, and Disraeli. Right in the centre of the aisle is a slab marking the resting-place of W. E. Gladstone and his wife (1898 and 1900), over whom unconsciously the people tread, gradually wearing out the simple words of memorial. The south transept is the Poets' Corner, containing the memorials from Chaucer to Ruskin. In the nave lie David Livingstone (1873), a great missionary and traveller, whose remains were reverently brought from Central Africa; Robert Stephenson (1859), the famous engineer; Sir Charles Barry (1860), architect of the Houses of Parliament; Sir G. G. Scott (1873); George Edmund Street (1881), architect of the Law Courts; Colin Campbell; Lord Clyde (1863), who recaptured Lucknow. We have mentioned these names, not for the sake of invidiousness, but have chosen them at random. Leading from the cloisters up a flight of stone steps is the Chapter House. The original structure was built by King Edward in the eleventh century, and it is noticeable in that it departed from the usual Benedictine form. In 1250 it was rebuilt by Henry III., and is an octagonal structure, second only to that at Lincoln in size. Here the monks were accustomed once a week to hold their chapters. In ornamental stalls opposite the entrance the Abbot and his four chief officers were enthroned, whilst the monks ranged themselves along the stone benches which go around the walls. Criminals were tried, and if found guilty were tied up to the central pillar of Purbeck marble (thirty-five feet high) and were flogged publicly. The monks, however, were not left in undisturbed possession of the Chapter House, for on the separation of the Houses of Lords and Commons in the reign of Edward I., the House of Commons held sittings here and continued to do so till 1547. The last parliament held here was on the day that Henry VIII. died, when it sat to discuss the Act of Attainder passed upon the Duke of Norfolk. At the dissolution of the monastery the Chapter House passed to the Crown, and seven years afterwards the House of Commons removed to St. Stephen's Chapel in the Palace of Westminster.
