What Is a UNESCO World Heritage Site?
A UNESCO World Heritage Site is a place recognized by the United Nations Educational, Scientific and Cultural Organization (UNESCO) as having outstanding cultural, historical, scientific, or natural significance.
These sites are protected because they represent some of the most important places on Earth. In the United States, UNESCO sites range from ancient Native American settlements to iconic national parks and architectural masterpieces.
Types of UNESCO World Heritage Sites
UNESCO World Heritage Sites fall into three categories:
Cultural Sites
Historic landmarks, cities, archaeological sites, architecture, and cultural landscapes.
Natural Sites
National parks, ecosystems, geological formations, and wilderness areas.
Mixed Sites
Rare destinations that are recognized for both cultural and natural significance.

Near present-day St. Louis sits the largest pre-Columbian settlement north of Mexico. Around 1100 CE, Cahokia was one of the largest cities in North America, covering more than 4,000 acres with massive earthen mounds and a population estimated at 20,000 people.

The central construction consists of six rows of concentric ridges, parts of which were as high as five feet.
Moravian Church Settlements
