301 N. 11th (City Park). A gray granite 1910 fountain stands as a testament to an early Seneca mayor who persuaded Hermon Lee Ensign, founder of the National Humane Alliance, to donate one of his fountains to the town. Between 1906 and 1911 Ensign donated 125 fountains nationwide to provide drinking water for horses and other animals. One of the few remaining in the country, the Seneca fountain originally stood at 3rd and Main.
