"Yesterday a street was solemnly unveiled in Vilnius, named after late Polish President Lech Kaczynski, may he rest in peace," the Polish Foreign Ministry wrote on Twitter, retweeting Lithuanian Foreign Minister Linas Linkevičius' post.
"Minister Linkevičius, thank you for this gesture and for remembering that the 100th anniversary of Poland's independence is approaching," the ministry wrote.
It also shared a video of Lithuanian President Dalia Grybauskaitė congratulating Poland on this occasion.
A sign marking the street named after Kaczynski was unveiled on Thursday, and a square also named after the late Polish leader has been unveiled in Maišiagala, a town some 25 km north west from Vilnius.
President Kaczynski, his wife and many other high-ranking Polish officials died in a plane crash in Russia in 2010.
The City Council of Vilnius last February decided to name the nameless street next to the municipality building after the neighboring country's late president.
