Budapest’s Chain Bridge will be lit in blue and white, the Scottish national colours, on Friday and Saturday, in honour of that country’s national holiday, St Andrew’s day. Iain Lindsay, the UK’s ambassador to Hungary, will address a short ceremony on Eötvös Square before the lights are turned on. The Chain Bridge will be lit from afternoon until midnight on both days. The building of Budapest’s iconic bridge and the Castle Tunnel were overseen by Edinburgh-born engineer Adam Clark.
