Duket Architects is currently working with the Toledo Harbor Lighthouse Preservation Society in its quest to preserve and restore the historic lighthouse. Located 8.4 miles from the mouth of the Maumee River, marking the entrance to the Toledo harbor, the 85 foot high Romanesque four-story brick lighthouse with attached fog signal annex building provides many opportunities for reuse of approximately 4,000 square feet, while still remaining an active guide to maritime activity.
