The oldest building in Wichita, Kansas is the Munger House, also known as the First Wichita City Hall. The house was built in 1870 by Darius Munger, who was a prominent early settler in Wichita. The building was constructed using bricks made in Munger’s own brickyard, and it served as a private residence for several years before being purchased by the city of Wichita in 1874 to serve as the first city hall.

Over the years, the Munger House has served various other functions, including as a public library, a museum, and a community center.

Today, the building is listed on the National Register of Historic Places and is owned by the Wichita-Sedgwick County Historical Museum. The house has been restored and is open to the public as a museum showcasing the history of Wichita and Sedgwick County.
