- The Warsaw Citadel was build by the Russians during the years 1832 to 1843. The construction of the fortification was started after the Russian military had suppressed the November uprising. Originally the Citadel was known as a Alexander's Citadel, according to the Russian Tsar of that time and the Citadel was intended to keep the rebel city obedient to the Russian authorities.

- During the years of the annexation of Poland, the Citadel served as prison for the Polish political prisoners. Approximately 40 000 prisoners were kept here. They were people who were fighting for the Polish independency and for the social changes in the country. 

- A few hundred of these prisoners were executed at the Citadel slopes. Additionally, many thousands of them were sent to the endless labour camps in Siberia.

- After Poland regained it's independency in 1918, the new Polish army took over the Citadel. It was used as a garrison and a training ground for the infantry. Additionally ammunitions and weapons were stored here for the army. During the Warsaw uprising in 1944, some battles were fought near of the Citadel, when the German garrison prevented the Polish Home Army from the center of the city of linking up with other units in the northern districts of Warsaw.

- The Citadel however survived the total destruction of Warsaw and after the war, the Citadel was again taken over by the Polish Army. Today the Citadel holds a museum, but some parts of the fortification are still in use by the Polish Army. Some parts on the other hand, seems to be abandoned completely...

- One of the giant gates to the Citadel. The place is absolutely huge, I think it took about an hour for us to walk around the place.

- An old sewer network still goes in front of the Citadel. Not much water there and the little amount that still goes in this canal, is very muddy water.

- Outside of the main walls, stands some defensive structures which have seen better days. Some are burned badly and others have been vandalized. The sturdy doors do keep people away from the interiors and one day, these doors will be rusted to the point, where no one will be able to open them.
