Port Clinton, the county seat, is home to the present Ottawa County Courthouse, completed on May 20, 1901 and listed on the National Register of Historic Places in 1974. Constructed in the Richardson Romanesque style, the courthouse exterior was built with sandstone quarried at Amherst, Ohio. Pink marble wainscoting, an ornate staircase, and stenciling enhance the interior. A copy of William Powell's mural, "Perry's Victory on Lake Erie," appears there along with smaller murals depicting early county industries: farming, fishing, fruit growing, and quarrying. Memorial tablets honor veterans of the Spanish-American War and Civil War.
