8 Oldest Founded Towns to Visit in Illinois

When people think of Illinois, they immediately may think of Chicago. America's 21st state is more than just Chicago's bustling streets and brightly lit skyline.

Archeologists believe that humans lived in the state for at least 10,000 years, with communities like the Miami and the Illinois Peoples inhabiting the lands before the European arrival. History-loving tourists can discover Illinois' storied past by visiting some of its oldest towns, which are still thriving in modern times today, from Alton to Cahokia.

Crebs, James Robert Williams, Orlando Burrell, and Roy Clippinger. White County's former courthouse is still found in Carmi, a double-pen log cabin built in 1814.

Before European settlers came to Peoria, the area was home to several Native American communities. In fact, they named the area Pimiteoui, or "fat lake," due to its abundance of resources. In 1691, Fort Pimteoui (the modern site of Peoria) was established after French explorers Jolliet and Jacques Marquette saw great potential in the area due to its natural resources and ideal strategic location. By 1819, the first American pioneers settled in Peoria, eventually incorporated by 1845.

Visitors can explore centuries of history at Peoria, learning more about the town's past at the Peoria Riverfront Museum, the Springdale Cemetery, and the Peoria Historical Society. Historical bus tours can also be taken with certified tour guides!

Prairie Du Rocher is located 50 miles south of St. Louis. Translated, the town's name means "Prairie by the Rock." This town was founded as a village in 1722 as a fourth European settlement in Illinois. Prairie du Rocher was a vital stop between New Orleans and Quebec, alongside Fort de Chartres. 

Today, some residents of Prairie Du Rocher can trace their lineage back to the first French settlers. Even the town's historic landmarks incorporate both elements of French and American design. History-loving tourists can explore and discover landmarks like the Creole House. The Saint Joseph Cemetary also includes the burial places of the French Illinois Colonists and a memorial tombstone to commemorate several communities and victims of violence.

Shawneetown

Shawneetown lies in southern Illinois in Gallatin County. Though the town was established in 1810, its area was the location of a former Shawnee village and the site of ancient Native American burial grounds. Once it was founded as a settlement, Shawneetown was regarded as a hub for trading, finance, and settlers coming from the East. Shawneetown was an essential settlement in Illinois at the time, along with Kaskaskia. Despite its success, the town suffered from repeated flood events, especially during the 1937 flood that flooded the town with 15 feet of water. Devastating the town's infrastructure, Shawneetown's buildings were relocated three miles northwest. Inhabitants that refused to move and infrastructure that was not transferred were established as Old Shawneetown in 1956. Curious travelers can take a historical walking tour to explore historic buildings like banks, churches, and homes.

Kaskaskia

The French Colonial Village of Kaskaskia is one of the state's oldest communities. The Illinois and Iroquois Peoples inhabited the area before it was founded as a village in 1703. However, the village quickly grew in prosperity due to its fertile land and proximity to the Mississippi River. Thus, Kaskaskia quickly became a center for agriculture and fur trading. By the early 19th century, the town reached a size of about 7,000 and was eventually incorporated in 1818. The same year, at the time, it was declared the capital of Illinois.

Kaskaskia became an island along the new channel cut by the Mississippi River due to flooding events, especially in 1881. The community is the only one in Illinois that sits west of the Mississippi River. Visitors can only access Kaskaskia Island through St.Mary in Missouri.

Cahokia

Cahokia was located in St. Clair County of southwestern Illinois, situated along the Mississippi. This Illinois town was one of the oldest towns in the state, founded in 1669 by Quebecois missionaries. Its name means "wild geese" and was named after the Illinois peoples that resided in the area around the 18th century. Cahokia was the first permanent European settlement in Illinois and was a hub for French influence around the upper Mississippi River Valley. The settlement stopped existing when it was incorporated into the new city of Cahokia Heights on May 6, 2021.

Situated a few miles from Collinsville, the Cahokia Mounds are a significant remnant of Illinois' storied past.
