Located on more than 100 acres in NE Oklahoma City, the Oklahoma State Capitol is the only capitol in the world surrounded by working oil wells. One is even named Petunia #1, because it was drilled in the middle of a flower bed. The architecture is Greco-Roman and the structure comprises 650 rooms and 11 acres of floor space with murals, restored stained glass, tribal flag plaza and changing art exhibits. The current site was chosen in 1915 and construction was completed in 1917. Construction of a dome was completed in 2002, a feature that was included with the original design plans of the building but never completed. Self-guided tours are available Mon-Fri 8am-5pm. A 45 minute guided tour is available every hour on the hour from 9am-3pm, Mon-Fri, or a two hour guided tour is available for adults by appointment, Mon-Fri. *
