The Sanctuary contains the last free-flowing section of Bull’s Run creek, which marked an original boundary of Middletown plotted in 1802. The area was used as a grazing pasture for bulls in the mid-1800’s. Bull’s Run Corporate, a non-profit corporation, now manages this city park. Visitors are likely to see squirrels, a variety of birds, perhaps a box turtle and an occasional deer. Spring provides many woodland wildflowers. In Autumn the display garden of Ohio Native Plants reaches its blooming peak. Eight bird-feeding stations are maintained during winter for easy bird viewing.
