The Tennessee State Capitol, located in Nashville, Tennessee, is the seat of government for the U.S. state of Tennessee. It serves as the home of both houses of the Tennessee General Assembly–the Tennessee House of Representatives and the Tennessee Senate–and also contains the governor's office. Designed by architect William Strickland (1788–1854) of Philadelphia and Nashville, it was built between 1845 and 1859 and is one of Nashville's most prominent examples of Greek Revival architecture. The building, one of 12 state capitols that does not have a dome, was added to the National Register of Historic Places in 1970 and named a National Historic Landmark in 1971. The tomb of James K. Polk, the 11th president of the United States, is on the capitol grounds.
