Courthouse Square Park is a town square occupying one city block in downtown Dayton, Oregon. The {{convert|1.8|acre}} urban park is listed on the National Register of Historic Places. The park contains the historically significant blockhouse or military fortification that was originally located at Fort Yamhill.{{NRHP url|id=87000336|title=National Register Information System}} In 1911, the structure was moved to Dayton from its original site. The land for the park was donated by Joel Palmer and the park was named 'Courthouse Square' as part of an attempt to make Dayton the government seat of Yamhill County. Although Dayton did not become the county seat and no courthouse was ever constructed, the park's name remained. The Park also contains a picnic shelter, grassy areas shaded by Douglas Firs and native oaks, a basketball court, a playground and public restrooms.[http://www.ci.dayton.or.us/vertical/Sites/%7B0813AE62-E15F-4C65-858B-10DDF2ABA1FE%7D/uploads/%7B5BEE5E01-696F-430F-859E-89E63F51FC75%7D.PDF Dayton Centennial Commission Report]
