The huge Irish contribution to building today's London has been marked by a short video, 'We Built This City,' a project completed by the Irish Architecture Foundation as part of Irish Design 2015. It is a lovely piece, something we can all be justifiably proud of. So many of us either emigrated ourselves, or had family or friends who left home to seek 'fame and fortune' in Britain, America, Canada, Australia and many, many other places. Many of us did OK, worked hard, made some money, settled down, or maybe even returned. Many others did not fare so well, running afoul of poor working conditions, dangerous workplaces, uncaring employers, or just the perils of emigration, pain, loneliness, alcoholism, and ill-health. Spare a thought for all of those emigrants as you watch this short, inspiring video.
