Tazumal () is a pre-Columbian archeological site in Chalchuapa, El Salvador. Tazumal is an architectural complex within the larger area of the ancient Mesoamerican city of Chalchuapa, in western El Salvador. The Tazumal group is located in the southern portion of the Chalchuapa archaeological zone. Archaeologist Stanley Boggs excavated and restored the Tazumal complex during the 1940s and 1950s. Archaeological investigations indicate that Tazumal was inhabited from the Classic period through to the Postclassic and that the site had links as far afield as central Mexico, the northern Yucatán Peninsula and lower Central America. Metal artifacts from the complex date to the 8th century AD and are among the earliest metal artifacts reported from Mesoamerica. Location Tazumal is situated within the municipality of Chalchuapa in the department of Santa Ana, within the Río Paz drainage basin. The ruins are at an altitude of above mean sea level. It is about from the contemporary Maya city of Kaminaljuyu. Tazumal is southwest of the small Late Classic site of Alumulunga. History Chalchuapa was inhabited since the Preclassic period, when massive construction activity took place. Around the boundary between the end of the Late Preclassic and the start of the Early Classic, construction at Tazumal was interrupted by the eruption of the Ilopango volcano, some to the east of the city. This eruption caused a hiatus in construction activity at Tazumal that may have lasted several generations. Activity resumed during the Early to Middle Classic (c. AD 250-650) although the city never fully recovered to its Preclassic levels of activity. The Tazumal complex came closest to matching the enormous structures of the Preclassic period. The principal structures of the Tazumal group date to the Classic period (c. AD 250-900) of Mesoamerican chronology. By the Late Classic (c. AD 600–900) Tazumal was an important ceremonial complex. Construction activity is evident from the Early Classic through to the Middle Classic (c. AD 400–600). At this time Tazumal had important links with the Maya city of Kaminaljuyu in the Valley of Guatemala, which acted to extend the influence of the powerful central Mexican city of Teotihuacan into the Pacific coastal areas of Guatemala and El Salvador. During the Late Classic Tazumal had links with Copán in Honduras, as evidenced by architecture, sculpture and ceramics at Tazumal. The ceramic sequence at Tazumal continues uninterrupted from the Classic period through to approximately AD 1200. A number of Early
