Restoration


year completed

Ongoing

Iolani Palace was built from 1879 to 1882 during the reign of King Kalakaua. Constructed of plastered brick and adorned with six Italianate towers, the Palace grounds are surrounded by a plastered coral block wall topped by an iron fence. Since 1980, MASON has served as project architect for 11 major phases of restoration work, supporting the preservation and interpretation of this National Historic Landmark and living reminder of Hawaii’s proud identity.

Throughout this comprehensive preservation project, our work included the restoration of the Old Archives (Kanaina) Building; restoration of the Coronation Pavilion, fences, gates and walls; reconstruction of the Barracks; improvements to Palace roofing, air-conditioning, and security systems; and the creation of gallery spaces in the basement.
