Trakai Castle is located on a peninsula on a peninsula formed by lakes Luka and Galve. For the construction of the castle was chosen a place that is on a remote place located between the swamps and lakes. Trakai castle was considered one of the most impregnable fortresses of defense of the 14th century in Lithuania, which was built during the great reign of Prince Kestuta. Castle building consisted of a central locking m predzamka.

The castle was located in an area of ​​4 hectares, and its exaltation took place just across the square: built simultaneously predzamok and part of it, adjacent to the hill. The most important role played predzamok, which is a large courtyard where the approach of the enemy, and gathered all the troops found refuge inhabitants of the castle. Predzamok was protected by thick stone walls with five towers.

The front part of the castle consisted of a courtyard in the shape of a quadrangle, which was surrounded by a defensive wall with different size towers. The tower, located a facade to the city, were located the main gate of the castle of Trakai. The most important was the south tower with buttresses. The tower has many loopholes, and the thickness of the walls is almost 4 meters. Judging by its architecture, size and location, it can be assumed that in the south tower could accommodate the owner of the castle.

During the Crusades enemies heading to Vilnius, tried to avoid the garrisons both of Trakai Castle, which existed simultaneously for some time.

Throughout 1382 the Teutons at once devastated the surrounding neighborhood of Trakai. In 1383 the enemy captured the castle, but could not long withstand the defense. The Crusaders brought to bombard the castle walls and fixtures for throwing stones. In the same year the Lithuanians conquered the castle, although it was badly damaged after many battles. In 1391 the castle along with the town were burned. Trakai castle destroyed not only the fault of the Order, but also as a result of fratricidal wars between the great princes of Latvia. Almost ruined buildings have often been the strengthening and rehabilitation.

In the early 15th century, the dilapidated castle was fortified with the help of another wall and a small adjacent towers. We know that the wooden walls of the castle of Trakai were replaced with stone in the 15th century. Thus, on the hill there was a stone building, and it was attached to the courtyard, surrounded by walls. Near the foot of the hill it was created moat that is 12 meters wide and strengthened walls made of stone. In carrying out the construction work was used with brick, which in some places is completely hidden core of the old stone walls. Trakai Castle belongs to one of the largest castles of that time in Lithuania. As for the art of construction, shape and design of the castle, they are almost indistinguishable from the castles of defensive architecture of the European sample.

Time passed and Trakai Castle ceased to be a reliable protection, because to him it was easy to approach, and constantly developing military technology has become capable of destroying even the thick walls of the castle.

After the Battle of Grunwald was decided to build a stone fortress near Lake Galve. But the idea was never realized in life. Not completed and the construction of a palace on the sacrificial mountain. After Vytautas died, the work stopped immediately. Later, after a devastating war with Russia in 1655 on the 1661 castles ceased to recover completely. In the 18th century in the castle settled Dominican monks. Soon they began to build a church, but they did not have enough money and there neotstroennom church chapel and convent.

As soon as Lithuania lost its statehood and became part of Tsarist Russia in 1795, not only the castle, but the Palace of the Vilnius Lower Castle, it was completely destroyed in the early 19th century. Approximately 4 hectares of the former grounds of the castle have been converted into a park. Today, after a partial restoration, often hosts local holidays.
