Many official buildings built in the US are very strongly influenced by Greek and Roman architecture. The most obvious being the White House, which displays Roman and Greek influences in the arches and columns on the exterior, and in the windows seen on the White House.

Many Greek designs still resonate and "echo" into modern western architecture to this day.
Hope this helps :)
