Calimaya is a town and municipality located just south of Toluca, the capital of the State of Mexico in central Mexico. The settlement was probably established around 800 BCE, when the city of Teotenango was in existence. It remained an important town through the colonial period, part of the vast lands held by a family which came to be known as the Counts of Calimaya. The town is home to one of the oldest examples of an open chapel in the State of Mexico. Today, the municipality is still mostly agricultural but there has been a rapid construction of housing divisions, changing parts of it from rural to suburban.
