The Saski Palace, also known as the Saxon Palace, was one of Poland's most distinctive buildings prior to World War Two. It was destroyed by Nazi bombing in 1944, along with much of Warsaw, after a failed uprising led by the Polish resistance movement.
One of the only sections of the palace which still remains intact is the Tomb of the Unknown Soldier, a monument dedicated to unidentified soldiers who gave up their lives for Poland.
Prior to the war however, between 1930-1937, the palace was used by the Polish Armed Forces Cipher Office, according to AP News. It was during this time period that three mathematicians, Marian Rejewski, Jerzy Rozycki and Henryk Zygalski, cracked the German Enigma encoding machine.
The Enigma machine was an encrypted method of communication used by the Germans during World War Two, and the initial codes cracked by the Polish mathematicians laid the foundations for the wartime code-breaking carried out by Britain and their allies.
The Polish mathematicians created a copy of the German Enigma machine, known as the "Polish Enigma," and it was with this that they managed to read some 75% of all German Radio transitions by 1938, according to Polish news site The First News (TFN).
In the summer of 1939, at a meeting of French and British cryptologists near Warsaw, the Polish mathemeticians revealed what they had been working on, and passed on two of their Enigma machine replicas, one to the British and one to the French.
A British team working at Bletchley Park in the UK then used the information given to them in Poland in order to decipher the ever-changing German codes, something which could have shortened the war by up to three years, according to TFN.
Plans to rebuild the Saski Palace have always been in the background ever since 1945, although the rebuilding of Warsaw started with the focus on housing.
In more recent years, however, the foundations of the palace, as well as some other elements, were uncovered. Although this was supposed to lead to the rebuilding of the national landmark, the plans were put aside in the early 2000s, after experts said the old foundations were too weak to be built on, reports AP News.
However, at a ceremony this past Wednesday, President Andrzej Duda handed a law drafted by his office for the reconstruction of the 17th century building to the speaker of parliament for processing.
“Warsaw was being rebuilt for many, many years after the war, in times of poverty, of very modest living conditions, at the cost hard toil, and sweat and blood of the workers, the capital city was being raised from ruins," Duda said in his speech.
Once the Polish government have approved the plans and work can begin, the palace is expected to be completed by 2028, and will house culture and history projects.
