The Clayville Historical Site is located east of the town of Pleasant Plains, and is designed to illustrate pioneering life in the early 1800s. The main attraction is the Broadwell Inn, which was an old stagecoach stop on the Springfield to Beardstown line. It was built by Moses and John Broadwell in 1824 and is the 2nd oldest brick building in Illinois. Also at the site is the Batterton Cabin, which was built by Amar Batterton in 1817 and is the oldest surviving structure in Sangamon County. Other attractions include what may be the Obernagle Cabin and the last operating blacksmith shop in Springfield.
