I'm going to be called cia, mos, mi6, a shill, a slider, and a murderer for this post no doubt by piggy with the conch.
The Hapsburg seat of Vienna has a parliament building that was tossed up rapidly in 1861, and later greatly expanded to look an awful lot like the US Capital.
The US Capital went througha few iterations beginning in 1793, but by 1861 the two large wings and dome (an enhanced St Paul's dome if you're paying attention).
Guess who was president in 1861? It was Abraham Lincoln.
