One of the most eagerly awaited cultural buildings in Scotland (and possibly the UK) finally opened its doors last week – for a sneak preview at least – following an almost 10 year gestation, 4 years construction, and at a cost of £74m. And as architectural events go Glasgow’s new Riverside Museum by Zaha Hadid Architects, which stretches and soars out of the ashes of this former Clyde side shipyard, is no anti-climax. In fact this must be as good as it gets in terms of visceral museum experiences.
