In one of the most-talked-about moves this year, British outdoors retailer Mountain Warehouse opened their new William Street store on Saturday 2 May 2026, roughly a week after closing their old Mainguard Street shop.
They've gone to the former Treasure Chest building, which has had extensive safety refurbishment inside, while retaining features like the elegant staircase, and the ornate decorations on the outside of the building.
As in their previous store the product range is based around outdoor clothing and equipment. But here, as well as entry-level hiking, sportwear and accessories, walking boots, ski wear and camping equipment, they've got a far wider range of casual men's and women's fashions located downstairs, with most of the specialist equipment upstairs.
