MEXICO CITY (AP) — Google is adding interactive images of dozens of pre-Hispanic ruins to the "Street View" feature on its Google Maps website.

Google Mexico and Mexico's National Institute of Anthropology and History announced Thursday that 30 sites have been added to Street View, and dozens more will be coming online this year. The eventual goal is 90 sites.

The feature allows users to click on map locations to obtain 360-degree, interactive images composed of millions of photos taken at street level by specially equipped vehicles. Google uses a special, three-wheeled bicycle to generate images of the Mexican sites, many of which don't have paved areas.

The sites already online include Chichen Itza, Teotihuacan and Monte Alban.
