The Ankh-Morpork Central Post Office had a gaunt frontage. It was a building designed for a purpose. It was, therefore, more or less, a big box to employ people in, with two wings at the rear, which enclosed the big stable yard. Some cheap pillars had been sliced in half and stuck on the outside, some niches had been carved for some miscellaneous stone nymphs, some stone urns had been ranged along the parapet, and thus Architecture had been created.
