Sturgeon Bay Ship Canal Lighthouse
Sturgeon Bay Ship Canal Lighthouse design was experimental and consisted of just the central column with a lantern and watch room perched on top. The hope was that this was going to be a simple, economical way to build a lighthouse for the future. Unfortunately, it didn't work out that way. It was discovered very quickly that the lantern vibrated from the movement of the tower in the wind and that made it impossible to keep the light turning on time. Several attempts were made to correct the problem and ultimately, they ended up adding the bracing you see on the lighthouse today. The tower was originally built in 1899 and the bracing you see today was completed in 1903. -from Wikipedia
