The fortress of the medieval period consisted of a closed fence in the form of walls and towers. The main role of protection against attacks to the towers — they were the strongholds of the resistance. But with the advent of artillery these funds were not enough to protect, and the walls were fortified with additional structures, first built a Bastion or tower, then they evolved into bastions.
Defensive wall of the city of Vilna began to build by the order of Grand Duke of Lithuania in 1503, Alexander Built a wall all residents of the city, laid stone walls, installed the fence. Construction was completed in 19 years and was a structure with a length of about 3 kilometers with two defensive towers, which protects an area of approximately 100 hectares - the area of today's Old city, the average height of the wall was about 6, 5 meters. Originally the wall had five gates, but already in the beginning of the seventeenth century their number reached ten.
The development and growth of the city outside of the castle and the festering war between the Russian Empire and the Commonwealth for lands of Grand Duchy of Lithuania in the first half of the XVII century, wanted to strengthen the defense of the city. Then Vilnius defensive wall was reconstructed and near the gates subaceous on the hill boxto, was built further strengthened the fortification of land and the masonry of the Bastion.
It was intended to use artillery weapons to repel the enemy from the city. The Bastion had the appearance of a tower connected to a horseshoe-shaped part of a tunnel. The project, it is assumed, belonged to a military engineer Friedrich Getinto. It is difficult to determine the exact time of the construction of the Bastion, but archaeological excavations and plans of various years indicate that in the early seventeenth century it was already there. There is a record of the Vilna Governor Jan Unzila of 9 August 1627 on the inspection and verification of the technical condition of structures strengthening with reference to the Bastion, but did not specify her condition, which suggests that this structure was still fairly new.
In 1655 during the Russo-Polish war, the Russian army routed the enemy troops defending the approaches to Vilna, and took the city, defeating a small garrison in the city's castle. City's defensive wall and the Bastion of have undergone considerable damage in that period. To repair the damage was only in 1661, when, after 16 months of siege, the Polish-Lithuanian army managed to take the city by storm. But Northern war in the early 18th century again brought destruction defense structures of Vilnius.
In the mid-eighteenth century, the Bastion was still there, her designation is on the plan Furstenhof 1737, But in the later plans of the city from 1793 to 1862, not even a trace, only the tower is visible on the map 1793, which suggests that the Bastion is no longer of interest as a defensive structure and was not restored.
In the XVIII century, has suffered from wars and fires, the Vilnius defensive wall began to collapse quickly. It appeared numerous openings, manholes, done by the townspeople around her began to accumulate debris. No one cared about her recovery. The stones from the ruined walls was used mostly as a building material for houses and monasteries.
In 1799 the Russian Czar issued a decree for the demolition of obsolete and dilapidated fortifications of the city of Vilnius in order to "care and the extension of space". Soon most of the defensive walls and ditches were levelled.
In 1966, thanks to the archaeological and architectural studies began work to restore the Bastion. Rebuilt the tower, restored interior, the gun and the connecting tunnel.
In 1987, in bastee Museum was opened. It exhibited specimens of ancient weapons, and from the observation deck offers a beautiful panorama of the Old city.
