During the early stages of the northward expansion into what would become New Spain, specifically between the 1520s and 1540s, the town of Aculco and its surroundings were a significant transit area for colonizers and missionaries. For this reason, this part of the Royal Inland Road was referred to as the "Gate of Tierra Adentro," through which the regular movement of merchants, officials, ranchers, and livestock took place.

According to descriptions of the road from various historical periods, during the 16th century it was possible to find two royal roads between Mexico City and San Juan del Río: one on flat terrain and the other partially stony but shorter. Both roads diverged in San Juan del Río, making this stretch a significant point in the history of the Royal Inland Road.
