The Hawaii State Capitol's distinct architectural features symbolize various natural aspects of Hawaii. Among them:
- The building is surrounded by a reflecting pool, symbolizing the Pacific Ocean.
- The two legislative chambers are cone-shaped, symbolizing volcanoes that formed the Hawaiian Islands.
- The columns around the perimeter of the building have shapes resembling coconut trees. Also, there are eight in either side of the building representing the eight main islands of Hawai'i.
- When standing in the center of the structure, the chandeliers from both legislative chambers which represent the sun and moon can be seen through the glass walls
- The Capitol is built in an open-air design, allowing sun, wind, and rain to enter.
- The area that is normally reserved for a rotunda in most capitol buildings is left open to the sky. It is said that the sky is Hawaii's capitol rotunda.
