St Patrick's Day Parade in London
It’s important to be as green as possible all year round, but in March things get very emerald indeed when Ireland’s biggest celebration hits the city.
London’s St Patrick’s Day Festival (15-17 Mar) takes over Trafalgar Square with Irish food stands, art showcases and plenty of live music on a large temporary stage beneath Nelson’s Column.
There’s also a vibrant, boisterous parade (17 Mar) which winds through central London, starting at noon from Piccadilly.
It’s all in honour of Ireland’s foremost patron saint, who died on 17 Mar 461 AD and famously used Irish shamrocks to explain the Christian holy trinity.
