This weekend, in celebration of St. Patrick’s Day, Niagara Falls will be putting on its version of a “Kiss me I’m Irish” t-shirt.

On Sunday, March 17, the famous waterfall will turn green as part of its partnership with Tourism Ireland’s “Global Greening” campaign.

According to the Niagara Falls Illumination Board, the process happens thanks to hundreds of hundreds of LED lights that are housed in three locations across the Niagara Gorge in Niagara Falls, Ontario. The LEDs are a part of its year-round light shows but will turn green for this specific celebration.

“Together, these lights work to create a breathtaking view not to be missed and are illuminated every night of the year beginning at dusk,” the organization shared on its site.

According to The Daily Hive, Niagara Falls will be joined by several other iconic destinations as part of the “Global Greening” campaign. Those sights include the Sydney Opera House, Empire State Building, the Christ the Redeemer statue in Rio de Janeiro, the London Eye, the Colosseum in Rome and the Leaning Tower of Pisa.

Niagara falls, — both the American Falls and Canadian Horseshoe Falls — will turn the bright green color at 15-minute intervals at the top of the hour from 7 p.m. to 2 a.m. Sunday.

If you miss the St. Patrick’s day event fear not as there are still plenty of light shows to witness throughout the year.

In March alone the falls will turn a different color eight more times. On March 21, the falls will turn yellow and blue in honor of World Down Syndrome Day. On March 22, it will turn a brilliant shade of blue in honor of World Water Day. The following day, on March 21, it will once again turn green for ReRun’s Racehorse Adoption Awareness, and on March 24 it will turn red for World TB Day. For the entire schedule of light show events check in with the Niagara Falls State Park website.

And, as for this weekend’s St. Patrick’s Day event, just make sure to wear a little green to the show. Otherwise, you may get pinched.
