Legal's outdoor murals are the reason most visitors stop here. More than thirty large-scale paintings cover the exterior walls of buildings throughout the small downtown, depicting the area's French-Canadian and Métis heritage. The subjects range from early settler families arriving by wagon to scenes of fur-trade-era life to portraits of the community founders. The art ranges in quality but the sheer density — almost every commercial building has one — makes the whole town feel like an open-air gallery.
The murals are free to view and most are accessible from the main street. A walking map is available at the town office or from local businesses. The program has been ongoing since the 1990s and new murals have been added periodically, so the collection continues to grow. The best time to visit is in the warmer months when the colours are most vivid; winter light can be flat and harsh on the detail.
