Unionville rests in a hollow where the hills of Washington County begin their slow, patient rise from the Ohio River valley. It lies 14.0 miles north-north-east of Parkersburg, WV (from Parkersburg, WV: bearing 23°T), and is situated 2.6 miles north of Marietta. The land here is a quilt of green, stitched with the darker threads of mature woodlands and the brighter patches of cultivated fields. Creeks, like veins of silver, meander through the terrain, their banks often softened by a delicate fuzz of ferns and moss. The air, especially in the early mornings, carries the damp, earthy scent of soil freshly turned and the faint, sweet perfume of wildflowers that speckle the meadows. Sunlight, when it breaks through the canopy of oak and maple, falls in broad, golden shafts, illuminating the quiet dignity of the landscape. The story of Unionville is one of resilience and quiet industry, deeply rooted in the fertile earth and the enduring spirit of its people. For generations, the land has yielded its bounty, supporting a modest agricultural economy where corn and soybeans are king, but the smaller farms, with their heirloom vegetables and artisanal cheeses, also hold their place. The legacy of the region’s past is visible in the sturdy, weathered barns that dot the countryside, silent sentinels to a time when farming was the undisputed heart of Unionville’s existence. While the larger industries have largely passed this way, leaving behind only whispers of their former presence, a sense of self-sufficiency and a deep connection to the land continue to define the character of Unionville.
