Nothing made Nanking more celebrated abroad than the Porcelain Tower, called _Pao-ngăn tah_, or the ‘Recompensing Favor Monastery,’ which stood pre-eminent above all other similar buildings in China for its completeness and elegance, the material of which it was built, and the quantity of gilding with which its interior was embellished. It was erected by Yungloh to recompense the great favor of her majesty the Empress, and occupied 19 years (1411-1430) in its construction. It was maintained in good condition by the government, and three stories which had been thrown down by lightning in 1801 were rebuilt. The Tai-pings blew it up and carried off the bricks in 1856, fearing lest its geomantic influences should work against the success of their cause. As to its dimensions: Its form was octagonal, divided into nine equal stories, the circumference of the lower story being 120 feet, decreasing gradually to the top. Its base rested upon a solid foundation of brick-work ten feet high, up which a flight of twelve steps led into the tower, whence a spiral staircase of 190 steps carried the visitor to the summit, 261 feet from the ground. The outer face was covered with slabs of glazed porcelain of various colors, principally green, red, yellow, and white, the body of the edifice being brick. At every story was a projecting roof, covered with green tiles; from each corner and from the top of these roofs were suspended bells, numbering 150 in all. This beautiful structure was visited in 1852 by Dr. Charles Taylor, an American missionary, who has left a full account of his observations.[47] It was to have been raised to an altitude of 329 feet and of thirteen stories, but only nine were built; careful measurement gave 261 feet as its height, 8-1/2 feet its thickness at top, and 12 feet at the base, where it was 96 feet 10 inches in diameter. The facing was of bricks made of fine porcelain clay; the prevailing color was green, owing to the predominance of the tiles on the numerous stories. The woodwork supporting these successive roofs was strong, curiously carved and richly painted. The many-colored tiles and bricks were highly glazed, giving the building a gay and beautiful appearance, that was greatly heightened when seen in the reflected sunlight. When new it had 140 lamps, most of them hanging outside; and a native writer says “that when lighted they illumine the 33 heavens, and detect the good and evil among men, as well as forever ward off human miseries.” The destruction of a building like this, from mere fanciful ideas, goes far to explain the absence of all old or great edifices in China.
