Woodbury, founded in 1683 by Henry Wood (no relation to this CC), is the oldest town in the county.  National Park, another town in the county, was the site of the Revolutionary War Battle of Red Bank (now included in a county park) where Fort Mercer once stood. Here can be seen the remains of the British ship Augusta (stored in a shed in the park), which sank during the battle. During the colonial era, Gloucester County's main economic activity was agriculture. In Woodbury (even then the main town) was located the county courthouse, the county jail, a Quaker meeting house (still in existence), and an inn (on the current location of Woodbury Crossings). Because of the county's many creeks leading to the Delaware River and the Atlantic Ocean, smuggling was very common.
