At the present time no traces of house or temple walls are to be seen, and the stone facings have even been stripped off the foundation mounds, for the whole group of ruined buildings has long been treated as a quarry by the people of Santa Cruz. There can be no doubt that this group of mounds represents the guard-house or Castle of Resguardo; but it is quite clear from the plan that the buildings were of the same nature as those found throughout the country, and they stand grouped together in the usual manner. The position they occupy is a naturally strong one, and would offer great facilities for defence, but there is nothing especially characteristic of a fortress about the buildings themselves.
After leaving this hill a walk of about two hundred yards brings one to the edge of the barranca and to the narrow natural causeway by which alone the city or stronghold of Utatlan could be approached. On crossing this narrow bridge one finds oneself on a fairly level space of ground about eighteen acres in extent, with almost precipitous sides, over which one can look down to the bottom of the barranca four hundred feet below.
