Purpose
To provide a place of focus for the public to learn about the natural and cultural history of the Olentangy River and of Terradise, the 18-acre plot of Olentangy/Whetstone River bottomland. Permanent and temporary displays will tell the story of the river and Terradise. Exhibits showing the natural flora and fauna as well as the unique riverine habitat will be on permanent display. Temporary displays such as art produced by the Terradise Environmental Arts Residency Grants, local artists and naturalists, and other relevant materials will be welcomed. The Interpretive Center will serve as a gathering point for visitors to both sides of the river (The Marion County Parks’ Terradise Nature Preserve and the Terradise Nature Center).
Background
Terradise was purchased from Marie Thomas in 1952 and the Trella and Ray Romine residence was built in 1953. Ray was a poet and coined the term “Terradise” as “Heaven on Earth” (Terra + Paradise). Sheep had grazed the site, but the native plants soon recovered and now over 80 species can be found, including some which are rare or endangered. Fauna include beaver, otter, deer, raccoon, squirrel, voles, chipmunks, various salamanders, fish, and amphibians. Bird lists have included over 50 species over the years. Great Blue Herons and Bald Eagles regularly fish the river.
While Trella Romine lived in her home (1953-2013), Terradise hosted many club meetings, garden club tours, and events, and encouraged visits for fishing and hiking. Since the Nature Center was formed in 2018, annual visitation has risen every year and we now see over a thousand visitors per year, including those who choose to stay at the Romine residence for overnight visits. In addition, events such as the Terradise Environmental Arts programs and the Tunes at Terradise Concert Series have attracted broader participation in experiencing Terradise. We expect the Interpretive Center to be a destination site, with the unique architecture attracting many new visitors, even in inclement weather.
The 18 acres of Terradise and the two acres across Whetstone River Road boast three habitats: prairie, woodland, and wetland/floodplain. The area was designated an Ohio Natural Landmark by the Ohio Department of Natural Resources and serves as a recreational facility for the village of Caledonia and Marion and Morrow Counties. The Jr. River Patrol Landing provides river access for kayaks and canoes, with ample parking. Having an interpretive center will allow our exhibits to be viewed year-round in a climate-controlled environment, with easy access on a level entrance from the parking lot.
The Building
To be built overlooking the river, with a roof garden deck for gathering and contemplation—dimensions of 30 ’x 30, single story with a unisex restroom.

Location
The Interpretive Center will be at the rear of the existing Trella Romine home at 1536 Whetstone River Road North, Caledonia, OH 43314 with easy access from the existing parking lot and a school bus drop off area:
Inspiration
Because of the desire for low impact on the area, the design will emphasize visibility of the surrounding area.
Naming
If a large donor does not claim naming rights, the proposed name of the Interpretive Center would be The Olentangy Watershed Interpretive Center.
