Cainta (historical polity)

In early Philippine history, the Tagalog bayan (Kapampangan: balen; "country" or "polity") of Cainta was a fortified upriver polity that occupied both shores of an arm of the Pasig River. It was located not far from where the Pasig River meets the Lake of Ba-i and is presumed to be the present site of the municipality of Cainta, Rizal.
