Acoma, a village of New Mexico, in lat. 35° 24' K, Ion. 106° 10' W., supposed by the abbe Domenech to be the Acuco of the ancient Spanish historians, and the oldest Indian town in the territory. It is built upon the horizontal summit of an isolated and almost perpendicular rock 394 feet in height. The greater part of the ascent to it is made by means of a road cut like a spiral staircase in the rock. The village consists of large blocks of houses, 60 or 70 in each block. It is said the Spaniards took the town from the Indians in 1599.
