Mariners' Village and Marina is a private community of custom homes featuring a harbor with direct access to the Illinois River. It is located in the small town of Seneca, Illinois.
Mariners' Marina features a man-made harbor that boasts 116 slips and is home to boats of all sizes during the summer boating season - cruisers, pontoons, ski boats, runabouts, and personal watercraft. The Marina slips float up and down with changing river levels and provide owners and renters with water, power, and other necessities. The Marina is located on the Marseilles pool which runs about 27 miles between the Dresden and Marseilles locks.
A privately owned Clubhouse, shown in the picture below, graces the harbor and includes bathing and laundry facilities as well as a large pool and sauna. Two large decks overlook the pool, harbor, and Illinois River. The pool and lower level facilities are available to Mariners' Marina boaters.
