Ireland's national holiday, celebrated worldwide with Irish stew, soda bread and the country's most famous export, Guinness stout.
Marking the death of Ireland's patron saint, St Patrick's Day has grown from a religious feast day into one of the most widely celebrated national holidays anywhere in the world, observed with parades and Irish food and drink in cities from Chicago to Tokyo as much as in Ireland itself.
In Dublin, the festival now runs across several days, with traditional dishes like Irish stew, colcannon and soda bread served alongside the country's best-known export — Guinness stout, poured in extraordinary quantities across pubs worldwide on the day itself.
