- The earliest history of the castle is connected with the establishment of a Seat of Castellan in the 12th century. Originally the stronghold was fortified with only wood and earthen bulwark. The defensive tower which can be still seen inside the castle, was build in the 13th century.

- As the tower had been build from the bricks, the surrounding castle was also designed again and a brick walls along with ramparts were build in the 14th century. The Gothic Church which also stands inside the castle, followed the design of the castle and was build during the reign of Casimir the Great.

- During 1520's, the castle was completely renewed and turned into a royal palace. It was inside the new magnificent palace, where the historical meeting of the Polish parliament was held in 1569. In the meeting the parliament voted for a union with Lithuania and thus creating a true super-power of it's time.

- During the wars in the 17th century, Lublin Castle like many castles in Poland fell into ruins in the hands of the Swedish army. Only the oldest sections of the castle remained intact, but despite of this, the castle was build all over again in 1824 to 1826. After the construction had been completed, the castle was turned into a prison. From 1835 to 1915, mainly Polish people who had taken part of the struggle for independency were jailed here by the Russian Tsar's. After Poland had regained it's independency, people from the communist movement served their sentence here.

- The most well known prison functioned in the castle from 1939 to 1944. The Germans imprisoned Polish people in the castle, suspected of carrying out political or military activities against the Germans. During the time that the prison worked under the Nazi regime, some 40 000 people passed through it's gate. Many of them died as a result of the executions or in the death camps to where they were sent from the Lublin Castle. On the eve of the liberation 22nd of July 1944, Germans killed 300 prisoners inside the castle walls.

- After the Germans were gone, the Russians established a harsh political prison to the Lublin Castle. Poles suspected of fighting against the communist rulers were held in the castle. The prison was dissolved in 1954. During the time that the prison existed under the Soviet rule in the Lublin Castle, some 35 000 Poles had been imprisoned there and about a thousand death sentences had been carried out.

- From 1957 onwards, the Lublin Castle has been the main seat of the Lublin museum.

- The old tower which dates from the 13th century. It's interesting to think how the old castle looked like? The tower does give some hints, but doesn't really fit too well to the much newer design.

- There's really nothing left to see from the time that the place was a prison. Only a sign which asks people the behave, in order to respect the memory of those who died here. The interiors of the castle holds a museums, which shows different kind of archeological findings in the area of Lublin.
