World goes green for St Patrick's Day

Some of Earth’s most famous sights – including the Pyramids of Egypt and Rio de Janeiro’s Christ the Redeemer statue – will be lit up green today.
The Sydney Opera House, Niagara Falls, the Leaning Tower of Pisa, Burj al Arab in Dubai, Table Mountain in South Africa, New York’s Empire State Building and Berlin’s TV Tower will be among others to pay tribute to Ireland with emerald lighting.
