Gate of Dawn The gate seen from the old town side Gate of Dawn ( Lithuanian : Aušros Vartai , Polish : Ostra Brama , Belarusian : Вострая Брама ) was built between 1503 and 1522 as a part of defensive fortifications for the city of Vilnius , the capital of the Grand Duchy of Lithuania . The name-sake for the gate was the borough of Ostry Koniec to which the gate initially led . It has also been known as the Medininkai Gate as it lead to the village Medininkai ( Polish : Miedniki ) south of Vilnius . The Gate of Dawn is the only remaining out of nine city gates , while the others were destroyed by the order of the government at the end of the 18th century .
