Falls Of Clyde and the Aloha Tower Named after a waterfall up the River Clyde in Scotland, the Falls of Clyde was built in 1878 in Port Glascow, Scotland. Falls of Clyde is the last surviving iron-hulled, four-masted full rigged ship, sail-driven oil tanker. Designated a U.S. National Historic Landmark in 1989. She is presently in storage with the hope to raise enough funds to restore her.
