This year's Saint Patrick's Day was celebrated during the past weekend worldwide.
On the day each year, the Irish celebrate the memory of Saint Patrick, the foremost patron saint of Ireland. It takes place each year on March 17 and has transformed from a day of feasting in the 17th century into a variety of festivals across the globe celebrating Irish culture with parades, special foods, music, dancing and a whole lot of green.

China
China's winding Great Wall turned green to celebrate St Patrick's Day in Beijing.
In addition to Beijing's Badaling Great Wall, a number of Chinese national icons have joined the global greening once again this year, including Canton Tower in Guangzhou, the Qujing 218 in Yunnan and the Culture and Arts Centre in Suzhou.
Meanwhile, several buildings took on green for the first time to celebrate the day in Hong Kong, including the Clock Tower and Cathay Pacific's DC-3 plane, otherwise known as "Niki," which went green to symbolize the number of direct air links now between the two countries.
