The U.S. Army Corps of Engineers Mississippi River Project invites guests to take a tour of the historic Clock Tower on Arsenal Island.

Relive the early days of the Rock Island Arsenal while climbing up the historic corridor of the Clock Tower Building, which has been a Quad-City landmark for more than 100 years, to see a spectacular view of the Mississippi River. 

The free 11/2-hour ranger-led tour will begin at 10 a.m. Saturday, Oct. 20, at the Mississippi River Visitor Center on the western end of Arsenal Island at Lock and Dam 15. Advance registration is recommended.

An adult must accompany children under 12 years of age. All persons over age 16 must carry a photo ID to enter the island.
