Bowen's mill, known today as the Yturri-Edmunds House and Old Mill, is believed to also date from the Spanish mission period, with a house added later by settlers who built on the secularized mission lands. Hendrick Arnold, a prominent black settler, hero of the Texas Revolution, and a member of Stephen F. Austin's famous "300 colonists," built a mill located on the San Antonio River in the township now known as Berg's Mill, in 1837. The mill was used for washing wool.
