Like many capitols in the US, Helena has its Lady Liberty atop the building, but the story of how it got there is really strange.
During the "capital fight", the people responsible for the plans ran off with all the papers and records. Then, during construction, a statue of a goddess of liberty arrived at the Helena train station from a foundry in Ohio, with no indications of who ordered it or for what use. With the building documents gone and the fact that the company who made the statue had all their records lost in a fire, there was no way to tell, and eventually, no one claimed the abandoned goddess. The builders wanted such a statue to put on top of their building, and that's how she ended up there.
