The historic Hebadin’a building was a trading post on and off for many years. It was last used as a store in 1981 and later was used for storage until December of 2002, when it became the A:shiwi A:wan Museum and Heritage Center. Records are unclear but it is thought the building was built about 1911. The original building was built slightly smaller than it is now and included a full size storage basement with a hand-operated elevator.
Between 1932 and 1935, office space was added to the south side of the building and the front was expanded about 1940 or 1941. The front addition was not perfectly constructed and a difference in elevations between the original storefront and the addition is obvious as you walk in and see the sag in the floor marking the carpenter’s obvious error. About 1940, Zuni artist Teddy Weahkee painted two sun faces on the outside upper face of the building entrance.
