 Once the dam was complete, the Company stepped up its promotional campaign, and the LDS Church encouraged members to move there.The town became predominately Mormon, and no church was ever built in Metropolis because the Mormons used the town amusement hall as a meetinghouse.In an attempt to demonstrate permanence, the Company built the amusement hall, a post office, a school, a train depot, and a magnificent modern hotel, complete with an electric generator, central heating, and hot and cold running water in every room.
