Steamship William G. Mather

Tour the Ship that Built Cleveland

Open May - October

Tour this restored 618-foot historic flagship and see what life was like onboard a working Great Lakes freighter. Explore the 1925-built Mather from stem to stern and see its huge cargo holds, brass and oak pilot house, elegant guest quarters and four-story engine room. Walk the decks and marvel at the “engineering firsts” that helped transform Northeast Ohio into a great industrial center. Experience the golden era of steamboats on one of the best.

View The Great Lakes Story exhibits, more than a dozen interactive experiences that tell how the Great Lakes were formed, what environmental threats they face, and how we’re using science and technology to help restore the health of these great bodies of water.

Please note that due to its historic nature, the Steamship Mather has limited handicapped accessibility. Learn more about the Mather.
