In the late 19th and early 20th centuries, many Nisg̱aa artifacts and treasures were destroyed or removed from the
Nass Valley by missionaries who established themselves along the Nass River. The Ancestors' Collection (
Anhooyaahl Gaangigatgum ) houses a core collection of over 330 artifacts returned to the Nisg̱aa from the
Royal British Columbia Museum, the
Canadian Museum of Civilization, and the
Anglican Church of Canada through the negotiated
Nisga'a Treaty. The entrance to the exhibits is through a replica of a Nisg̱aa longhouse which are exhibited in four galleries: • Transformation Gallery: an array of (
naxnok or spirits) masks and a celebration of the Nisg̱aa performers who brought these spirits to life. • Halayt Gallery: a display of items used by Nisg̱aa shamans to summon, focus, and direct supernatural forces. • Ayuuk Gallery: a chiefs box (or
hoohlgan) displaying the regalia and possessions that symbolize the social roles and structures prescribed by the Nisg̱aa laws and customs ("Nisg̱aa Code, or
Ayuukhl Nisg̱aa). • Living River Gallery: a display of possessions used in daily life in a traditional Nisg̱aa
longhouse, on the land, or along the banks of the Nass River (or
Lisims). Most of the artifacts are displayed in the open with only the most delicate or valuable behind glass, all secured by motion sensors. Included in the displays are four house poles (totem poles), representing the four Nisg̱aa clans, that were carved specifically for the museum. Future exhibits are planned to show both natural history and recent history of the Nisg̱aa people, including the struggle for the return of traditional lands and evolution into the self-governing Nisg̱aa Nation. Future additions are intended to include a variety of media including an audio guide, audio/visual presentation, museum book, a searchable database, archival software systems, a library and teaching centre, and a gift shop for Nisg̱aa art and artists. The
Ni'isjoohl totem pole is a tall hand carved totem pole. The pole was commissioned by the House of Ni’isjoohl in the 19th century to honor Ts'wawit, a Nisg̱aʼa warrior who had died in battle. During the summer of 1929, the pole was taken without permission by
Marius Barbeau and sent to the
Royal Scottish Museum. On September 29, 2023, the pole formally returned to the Nisg̱aʼa people and will be housed in the museum. ==Facilities==
