Built in 1938, the Federal Building has held many important people and organizations over the years. It's been home to state and federal leaders, the local post office and the FBI among others.
It stands tall at the entrance of Downtown Wausau, an imposing figure with more than 65 years of history behind it.
Historians say it's built for a feeling and holds a presence that many new buildings don't have.
That presence tends to stay with those who walk in to see a massive mural, marble lined walls and brass fixtures throughout the stairwells.
"Most people over 30 have been in that building at some point in time," says Kathy Anderson of the Wausau Historic Landmarks Commission. "Either paying bills, or picking up mail, or visiting offices."
The architects behind its design are responsible for many other historic buildings in town.
The offices of Senator Russ Feingold and Congressman Dave Obey were the last to occupy space in the building. It served as Wausau's post office for nearly 31 years, and came to be known as the Federal Building after that and ever since.
