The State Capitol building was built between 1914 and 1917 and is home to all three branches of State government and vast collections of State art. The State Capitol building had never undergone a comprehensive restoration despite its century of use and harsh Oklahoma weather.
The Project is a six-year, estimated $245 million restoration effort that will completely modernize the State Capitol building. The Project includes modernizing the building’s infrastructure and shoring up the limestone façade while
upgrading the functionality of the building for tenants and visitors alike. Investigation and construction
work began in 2015.
