In the year 1814, the business of the Post-Office had increased so greatly, that an agitation was commenced with the object of securing better accommodation for its despatch than was afforded by the office in Lombard Street. The first General Post-Office was opened in Cloak Lane, near Dowgate Hill, and removed from thence to the Black Swan in Bishopsgate Street. After the Great Fire of 1666, a General Office was opened in Covent Garden, but it was soon removed to Lombard Street, to a house which had been the residence of Sir Robert Viner, once Lord Mayor of London. It was now proposed that a large and commodious building should be specially erected in some central part of the City, and the business once more transferred. In the Session of 1814 we find a Mr. Butterworth presenting a petition to the House of Commons from four thousand London merchants, in favour of an early removal of the Post-Office from Lombard Street. He was assured, he said, that the present office "was so close and confined, as to be injurious to the health of those concerned;" he further stated, that "two guineas were expended weekly for vinegar to fumigate the rooms and prevent infectious fevers." Another hon. member stated that the access to the office was so narrow and difficult, that the mail-coaches were prevented from getting up to it to take the letter-bags. It is curious to note that even this change was contested. Counter-petitions were presented to Parliament, stating that the Lombard Street office was convenient enough, and that the movement was got up by interested parties. Many years passed before the discussions ended and the preliminary arrangements were made. Nothing could better serve to show the stationary character of the Post-Office than the fact that, year by year, and in the opinion of the authorities, the Lombard Street establishment sufficed for its wants and requirements. In 1825, however, Government acquiesced in the views of the great majority of London residents, and St. Martin's-le-Grand--the site of an ancient convent and sanctuary--was chosen for a large new building, to be erected from designs by Sir R. Smirke. It was five years in course of erection, and opened for the transaction of business on the 25th of September, 1829. The building is of the Grecian-Ionic order, and is one of the handsomest public structures in London. The basement is of granite, but the edifice itself, which is 400 feet in length and 80 feet in width, is built of brick, faced all round with Portland stone. In the centre is a grand portico with fluted columns, leading to the great hall, which forms a public thoroughfare from St. Martin's-le-Grand to Foster Lane.
