"We will sing the National Song all together on 100 Lithuanian hillforts and all over the world in the run-up to the centenary of the restored Lithuania," Prime Minister Saulius Skvernelis said in a press release.
"I invite everyone to join this great initiative and to encourage your friends and your family to sing the anthem -- if not on one of the selected hillforts, then at least among people close to them," he said.
Skvernelis plans to go to the Dubingiai hillfort for the traditional singing of the national anthem at 9 p.m. on July 6.
