It is amusing to notice, in the report of the Committee which considered the question of the new building, how afraid its members were that in the desire for beauty of style the question of utility would be neglected. Post Office architects have seldom needed this caution. “Ornamental decorations introduced for the mere purpose of embellishment, and unconcerned with utility, while they prodigiously enhance the cost, rarely produce an effect in point of elegance and grandeur which can compensate for it.” And yet again, “an office for the receiving and delivery of letters which should be concealed behind a front fit for a palace, and flanked by triumphal arches, would present an incongruity no less offensive to good taste than inconsistent with rational economy.” Here speaks the voice which in the early years of the nineteenth century produced so many evil results in street architecture. The architect of the new building was Mr. Smirke, and it is certainly to his credit that he was not unduly influenced by the recommendations of the Committee. The site covered two acres, and the clearance displaced a thousand inhabitants. It swept away numbers of alleys and courts, and when the building itself was opened in 1829 it at once took its place as a great addition to the architectural beauty of the City of London. Everybody who has visited London must be familiar with at least the exterior of the building. It was designed to meet the needs of the mail coach service, yet no sooner was the building opened than the sound of railways began to be heard in the land. But for nearly ten years the mail coaches started from St. Martin's le Grand, and traces of this era can be seen in the drive which goes round the building with an open courtyard at the north end. The Bull and Mouth Yard where the coaches were made up was opposite.
