Illinois covers an area of 149,998 km² (57,914 sq mi) [1]; it ranks 25th in size of the 50 states. Compared, Illinois is approximately half the size of Italy. Compared with other US states, Illinois would fit three times into California.


The main feature of Illinois' landscape are the fertile plains of the Central Lowland, which make up approximately 80% of the state's area. The Central Lowland is a part of the Interior Lowlands, which itself is a sub-region of the Interior Plains. North America's Interior Plains are the largest physiographic area in the contiguous United States. Glaciers created the vast flat region during the last Ice Age.

Within the Central Lowland lies the Illinois Basin with its sources of coal, petroleum, and other minerals.

Situated in the north west corner of the state is Illinois' portion of the Driftless Area, an area of rugged terrain that was not glaciated in the Ice Age. Within the Driftless Area is the state's highest natural elevation Charles Mound at 376 m (1,235 ft), located at the border to Wisconsin.

In the south of Illinois is the picturesque landscape of the Shawnee Hills. The Shawnee National Forest and the Ohio River Valley have become a major tourist destination.

Illinois has since 1982 a UNESCO World Heritage Site. The site is the archaeological remains of a pre-Columbian urban settlement of a mound-building Native American civilization. The urban center was located at the Mississippi River in southern Illinois between East St. Louis and Collinsville, across the river from modern St. Louis, Missouri.

The city's original name is unknown. Today the site is known as Cahokia Mounds State Historic Site; UNESCO official website it was the central section of a large ancient cultural and urban complex that existed from c. 600 to 1400 CE. It is assumed that the site was a political and religious center that attracted a variety of different Native American people from the plains.
In its heyday (between AD 1050 and 1100), Cahokia was the largest pre-Columbian urban center north of Mesoamerica with a population of more than 10,000 people, that number doesn't include the large population inhabiting outlying farmsteads and villages throughout the surrounding floodplain.

The huge settlement was located in a strategic position near the confluence of the Mississippi, Missouri, and Illinois rivers. The city featured platforms, ridgetops, and conical mounds; residential, and public areas; a large sundial and a (now reconstructed) palisade/stockade surrounding the central ceremonial precinct.
The pyramid-like mounds or terraces were constructed almost entirely of many layers of soil and clay. For ascending the sanctuaries, they featured ramps with log stairs.
Dominating the complex is Cahokia’s largest mound now known as the Monks Mound, it is the largest Pre-Columbian earthwork in the Americas and the largest 'pyramid' north of Mesoamerica.
