Three Crosses is a monument designed by Polish–Lithuanian architect and sculptor Antoni Wiwulski in 1916. It was torn down in 1950 by order of the Soviet Union authorities. A new monument designed by Henrikas Šilgalis was erected in its place in 1989.
There has been three wooden crosses on the hill at least since 1636. The origins of the monument are explained in a fictitious legend, written in the Bychowiec Chronicle among others, according to which seven Franciscan monks, who were invited to Vilnius from Podolia by Petras Goštautas, were tortured to death (crucified and thrown into the Vilnia River, according to some sources) on 4 March 1333 by local pagan inhabitants. The chapel was erected on the spot where they died and the crosses were added later on.
A spectacular panorama of the Vilnius Old Town can be observed from top of the hill.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
