The plate opposite represents the front of the same building. It is composed of two structures entirely different from each other, one of which forms a sort of wing to the principal edifice, and has at the end the facade before presented. The whole length is two hundred and twenty-eight feet, and the depth of the principal structure is one hundred and twelve feet. The only portion containing interior chambers, is that which I have called the wing. This has two doorways opening into chambers twenty-six feet long and eight feet deep, behind each of which is another of corresponding dimensions, now filled up several feet with mortar and stones, and appearing to have been originally filled up solid to the ceiling, making again casas cerradas, or closed houses. The whole number of chambers in this wing is nine, and these are all the apartments on the ground floor. The great structure to which the wing adjoins is apparently a solid mass of masonry, erected only to hold up the two ranges of buildings upon it. A grand staircase fifty-six feet wide, the largest we saw in the country, rises to the top. On one side of the staircase a huge breach, twenty or thirty feet deep, has been made by the proprietor, for the purpose of getting out building stone, which discloses only solid masonry. The grand staircase is thirty-two feet high, and has thirty-nine steps. On the top of the structure stands a range of buildings, with a platform of fourteen feet in front extending all round. From the back of this platform the grand staircase rises again, having the same width, fifteen steps to the roof of the second range, which forms a platform in front of the third range; this last is unfortunately, in a ruinous condition, and it is to be observed that in this, as in all the other cases, these ancient architects never placed an upper building on the roof of a lower one, but always back, so as to rest on a structure solid from the ground, the roof of the lower range being merely a platform in front of the upper one. The circumference of this building is six hundred and thirty-eight feet, and its height, when entire, was sixty-five feet. It seems to have been constructed only with reference to the second range of apartments, upon which the art and skill of the builders have been lavishly expended. It is one hundred and four feet long and thirty feet wide, and the broad platform around it, though overgrown with grass several feet high, formed a noble promenade, commanding a magnificent view of the whole surrounding country.
