"Structure 5, the Toltec style pyramid in Tazumal, in Chalchuapa, El Salvador. Also known as La Campana or the bell, it was constructed at the end of the Classic Maya period in 900AD, and then reconstructed and covered by concrete in the 40’s and now being restored. This pyramid faces a large game court, and as such likely represents the main structure of Tazumal.
Tazumal has traces going back several millennia but is best known for the population that started in 100AD until its abandonement around 1200AD. It represents El Salvador’s most important Maya site and covers no less than 10 square kilometers, much covered by the current (constantly encroaching) town. Artefacts recovered indicate that Tazumal traded with the well Known Maya cities In Mexico, but also suggest trade took place with places as far south as Panama.”
