The site of Kohunlich is relatively large, about 21 acres surrounded by tropical forest. The layout of the buildings and the remains of water-pipes and tanks suggests that Kohunlich was an important city in its time. On this site are close to 200 mounds, although many of them still remain inexcavados and invaded even by the vegetacion.2
archaeological information available suggests that Kohunlich received its first inhabitants near the year 200 A.D. , although the majority of the most significant buildings were developed between the year 250 and 600 a.d. Also it can be assumed that Kohunlich represented a focal point for the trade between the cities of the Yucatan Peninsula and several ancient Mayan cities in Central America.
The Building A-1 or of the masks is one of the most visited because it has monumental stucco reliefs that still preserve the red paint that covered the entire temple. It is likely that this building was built during the Early Classic period and has a greater relationship with the so-called Petén style.
The old name of the site is unknown. The word Kohunlich with which is called is not of Mayan origin, which is the result of a phonetic transcription of its original name in English Cohoon Ridge, that means Lomerio of corozos or Corozal, drawn up by the archaeologist Victor Segovia, who was the first to explore the region. The site is known since 1912 when the archaeologist Raymond Merwin visited the prehispanic settlement north of the Rio Hondo.
