Bicentennial Commons is an 11-acre park that overlooks the Great Miami River. The park features the brand new River Center, AK Pavilion, a portion of the Great Miami River Trail, a scenic overlook, and brick paver walkways. Most of the park was opened in 1990 to commemorate the 200th year anniversary of the City of Middletown. Management of the property was transferred from the city to MetroParks in the Spring of 2016. The River Center was constructed in 2017-2018 and opened for use in 2018.
