2. St. Pancras International, London, UK

Once facing neglect and near-demolition, St. Pancras International has emerged as a triumph of Victorian Gothic architecture. A sweeping £800 million renovation saved the station, transforming it into a vibrant gateway for Eurostar trains and international travelers. Its breathtaking ironwork and grand spaces now draw both commuters and tourists, setting a high bar for urban renewal. This revival has inspired similar restoration efforts, including the expansion of Paris’s Gare du Nord.
