Landmarks, buildings and places of interest around the world joined in the glow-up, with 670 landmarks across 66 countries taking part. Going green for the first time in the UAE are Dubai International Airport, Palm Jumeirah Monorail and the Sheikh Mohammed Bin Rashid Al Maktoum Centre for Cultural Understanding. The largest fountain in the world, Dubai's The Palm Fountain, also glowed in green and hosted a <em>Riverdance</em>-themed performance. Ireland's Pavilion at Expo 2020 Dubai and the recently opened <a href="https://www.thenationalnews.com/lifestyle/travel/dubai-s-address-beach-resort-jbr-review-hotel-insider-1.1170075">Address Beach Resort, Dubai</a> also took part in the global glow. Burj Al Arab, The Abu Dhabi Edition and the Hilton Garden Inn Ras Al Khaimah all joined in, too. Dubai's Burj Khalifa, the tallest building in the world, will glow green at 8.40pm on St Patrick's Day. Sydney Opera House joined Tourism Ireland’s Global Greening once again this year. The initiative first originated on St Patrick's Day in Australia 11 years ago when the famous landmark was illuminated in green. New attractions to join the effort include the most northerly "greening" in the world – a postbox at the summit of Oretoppen peak in Norway, 350 kilometres above the Arctic Circle. Other new places include the Torre Costanera in Chile, which is one of South America's tallest buildings; Bled Castle in Slovenia; Pacific Park on the Santa Monica Pier in California; and the Sekenani Gate at the Maasai Mara National Reserve in Kenya. These new sites joined others that have participated in previous years, such as the Leaning Tower of Pisa, Niagara Falls, Victoria Falls and the London Eye. "More than 70 million people around the world claim links to the island of Ireland and St Patrick’s Day is a truly unique opportunity to reconnect them with their heritage," said Niall Gibbons, chief executive of Tourism Ireland. "This year, against the ongoing backdrop of Covid-19, our St Patrick’s Day programme around the world is more important than ever before."
