Here's a view of Main Street, which looks very much the same today, except for the cars.
And here's a great view of the generator room at the power plant.
Here's a view of the Union Depot in better days. It's still standing, but has fallen into disrepair. The City of Keokuk bought the building in 2010 for $1 so they could add it to the National Historic Register, making it eligible for federal preservation grants.
The Hotel Iowa, built in 1913, is also still standing and was renovated in 2006.
