The downtown Santa Barbara Karpeles Manuscript Library Museum location that houses unique exhibits will officially close its doors for good on Sunday.

Longtime Director Norman Cohan called it bittersweet.

The closure comes as museum leadership looks to consolidate the multiple museum locations across the country into one in Florida, according to Cohan. 

Museum co-founder Marsha Karpeles and her son and CEO Mark Karpeles live in Florida.

While the museum at 21 W. Anapamu St. in Santa Barbara is set to close in the coming days, the building is still listed for sale for $3.3 million under commercial real estate company Colliers.

Colliers associate Mike Chung said he could not comment on whether the building has been officially sold, citing privacy reasons.

The closure ends the museum’s more than 40-year residency in downtown Santa Barbara showcasing historic documents such as the world’s first known peace treaty. 

The Santa Barbara location opened in 1984 and was one of many locations across the country under the nonprofit organization that houses “the largest privately-owned manuscript collection in the world,” which includes “more than a million historical documents.”

The collection would rotate between the museum locations across the country about three times a year. 

Just last month, Cohan didn’t know when the closure would happen, and some museum staff and regulars were hopeful of finding a way to keep it open. However, after Sunday, museum staff will be packing up the artifacts to send to Florida.

People can visit the museum for free through Sunday from 10 a.m. to 4 p.m.
