Cedar Rock State Park is a state park in Buchanan County, Iowa, United States, preserving the Frank Lloyd Wright-designed Lowell Walter Residence, also known as Cedar Rock. The Usonian-style house was constructed on a bank of the Wapsipinicon River near Quasqueton, Iowa, in 1950. Following Lowell Wa
lter's death in 1981, the home was donated to the Iowa Department of Natural Resources and opened to the public. In 2025, the Friends of Cedar Rock received a $50,000 state grant to finance the house's restoration. The Walter House at Cedar Rock is one of Wright's most complete signature designs. Nearly everything at Cedar Rock bears the architect's imprint. Wright designed the furniture, chose the draperies, and even picked out the accessories.
