Oklahoma State Capitol in Oklahoma City

Completed in 1917, the Oklahoma State Capitol in Oklahoma City immediately stands out because it's the only capitol grounds in the United States with active oil rigs on it. Also, while the original 1914 plans for the capitol included a dome, I was surprised to learn that it was only in 2002 that this addition was made to the structure. Restoration projects were ongoing during my visit, however it was still easy to get swept up in the grand architecture of the building.
