The Historic Hilltop Structures celebrate the history, heritage, and culture of the Ohio Valley, as well as the philanthropic families that made this park a reality. For residents, the cultural fabric of the community lives on here. And for all visitors from near or far, these cultural gems make a visit to Oglebay unforgettable. Through this campaign, we will build a new welcome and retail center, and revitalize the Oglebay mansion. The historic greenhouse will be expanded so it can grow food through aquaponics.
