The Market Square location features a special marine mammals gallery, which is home to "Delilah", a 40-foot North Atlantic right whale that beached off Grand Manan in 1992. Delilah's full skeletal remains are on display, hanging from the ceiling. Other galleries at this location include the only (and first) gallery in New Brunswick to be devoted entirely to New Brunswick, Canadian, and international art. Others allow you to take a geological trek through time, make a documentary in a fully equipped TV studio, play in the large hands-on Discovery Centre, or learn about the industries that shaped the province. The NB Museum houses the best collection of Loyalist artifacts on the North American continent, and the largest collection of ships' portraiture in Canada. In addition, it has a large natural history gallery, fine and decorative arts, and historical collections.
The newest feature is a tidal tube, found in the museum's lobby. Connected to the harbor, water in the tube rises and falls with the tide. This location also has ample space for traveling exhibits, a gift shop and bookstore, a full audio-visual theatre, a workshop, and lunch rooms.
