Where is the Kentucky State Capitol located?

The Kentucky State Capitol is located in Frankfort, which serves as the state capital of Kentucky. Frankfort was chosen as the state capital due to its central location in the state, which makes it accessible for citizens from various regions. The Capitol itself is an important historic building that houses the Kentucky General Assembly and the offices of the Governor and other state officials. Its construction was completed in 1910 and is known for its architectural beauty, reflecting the state's government and history.

The other locations listed, such as Louisville, Lexington, and Bowling Green, are significant cities in Kentucky but do not serve as the seat of government for the state. This distinction emphasizes the unique role Frankfort plays in the political and administrative functions of Kentucky, making it the correct answer.
