In 1963, Hogg purchased property near Round Top, hoping to move its historic building to Bayou Bend. When that plan proved impractical, she decided to restore it in place and temporarily moved to Round Top. After personally supervising the restoration of the Winedale Inn, a stagecoach inn near Round Top, Hogg donated the property to the University of Texas at Austin. Known as the Winedale Historical Center, it is used primarily as an outdoor museum and music center, and annually hosts Shakespeare at Winedale. In 1969, she restored her parents' house in Quitman; the town renamed it the Ima Hogg Museum in her honor. The museum holds items from the history of Wood County and northeast Texas. She later restored the home of her maternal grandfather and had it moved to the park.
