Almost a century after the missionaries, a museum was founded in 1931 by their descendents. In the late 1960s noted architect Vladimir Ossipoff designed and built a Museum building adjacent to the mission house. Upon its completion, the Museum moved there and expanded its exhibits. It has extensive displays on Hawaiian culture and is renowned for its collection of shells and minerals, including a specimen of orlymanite, named for Orlando Hammond Lyman (1903–1986), the museum's founder and great grandson of David and Sarah Lyman. The Museum has been an affiliate of the Smithsonian Institution since 2002.
