The iconic gold dome of the Iowa State Capitol has been one of the state’s most recognizable landmarks for more than 130 years. Over the course of its history, significant deterioration threatened the dome’s integrity. With funding from the Iowa Legislature, OPN Architects guided a project that involved replacing more than 12,000 interior bricks, building a barrier to protect the structure from moisture, restoring interior and exterior limestone, and building a monitoring system to assure the dome’s future for decades to come. This project is a cause for statewide celebration.
