It displayed none of those architectural embellishments and attempts at magnificence which usually centre about the _plazas_ of the Spanish-American capitals,--not even a carved door-facing or trifling ornament of any description. The entire side on our right, between the two eastern streets, was occupied by the cracked and roofless walls of an ancient church or convent, which had long been a neglected ruin. The fallen stones and mortar had raised a sloping embankment high up its venerable sides; and the small trees, here and there shooting above the luxuriant grass and running vines which, covered this climbing pile of rubbish, waved their branches over the top of the mouldering walls. The interior of the crumbling structure was a wilderness of rank grass and weeds, the elysium of reptiles, iguanas, centipedes, and ten thousand poisonous insects. On our left, opposite the falling church, was another ruin; but its vulgar features owned none of the green and mossy dignity of age, which gave a melancholy beauty to the former. It was a glaring pile of naked dust and rubbish, and its shot crumbled walls and riddled doors told the tale of its destruction. The entire front on that side of the _plaza_ was in ruins, with the exception of one stout building on the corner diagonally opposed to us. The northern side was inclosed by a long, low building, with its elevated doors partly hidden by the far-projecting, red-tiled roof; and in front of it six or eight grim pieces of cannon, mounted upon wheels, gaped their black mouths toward us. Our own side of the square was occupied by a building exactly like the one opposite. The low-reaching roof was supported by wooden posts, and the long porch or corridor between the posts and the wall was paved with large earthen tiles. The doors, elevated several feet above this pavement to baffle the heat of a tropical sun, were darkened by the overhanging roof; and this, together with the effect of the small wooden-grated windows and the absence of furniture, gave the rooms a gloomy and comfortless aspect. All these buildings, with the exception of the ruined convent, which was of stone, were built of _adobes_, or large sun-dried blocks of mud; and their walls, doors, and staring red roofs were everywhere bruised or perforated with shot.
