During the first Music City Irish Festival in 2015, 10,000 people showed up for the free street fair.  - 

For some, St. Patrick’s Day is an excuse to drink green beer and pick four-leaf clovers. But for the country of Ireland, it’s a chance to conduct some global PR. And if some Irish festivals feel like travel ads for the Green Isle, that’s because they kind of are.

Drummers and dancers performed under tents to stay out of the rain at the inaugural St. Patrick's Day festival in Nashville last year. That event did get a little help from the Irish government, but nothing compared to this year: The country’s tourism and cultural agencies are footing a third of the bill, according to organizers.

Nashville's festival, which showcases Irish music, is one of several around the U.S. that the Irish government supports financially. Anne Anderson, the country's ambassador to the U.S., said it's because culture is Ireland's "calling card to the world."

"To present ourselves to the people of Tennessee through our music makes sense to us in very many ways," Anderson said.

Tourism is Ireland's largest indigenous industry, attracting 8.6 million overseas travelers in 2015. Put another way, more people visit Ireland each year than live there.

The country has turned St. Patrick's Day into a worldwide branding campaign. The number of iconic sites around the world that are lit in green for the evening grows each year. Nashville's Bridgestone Arena and Reunion Tower in Dallas joined the 2016 list for the first time.

Anderson said her country is putting new emphasis on making connections in the American South, and with Tennessee in particular. She pointed out that an estimated 14 percent of Tennesseans are of Scotch-Irish decent.  

The goal of the Nashville festival is to plant the seed that Ireland might be a nice place to visit or consider doing business, she said. 

“The correlation is not absolutely direct, and we don’t expect it. It’s not an absolutely calculating investment in that way,” Anderson said. “But it’s to make them familiar with Ireland. Feel good about Ireland. Feel inspired about Ireland. And to lodge a thought about, 'Why not Ireland?'”

But festival founder Brenda Willis says the money comes with strings attached.

“They always tell me,” Willis said, “'the whole reason we do this is bums in seats. We want bums in seats on airplanes going to Ireland.  If that’s not what we’re getting out of this, we’re going to pull our funding.'"

Willis says her Irish backers even track airline travel originating from cities where they’ve invested in St. Patrick’s Day celebrations to see if they’re getting a return on the investment.
