The Hungarian korona (Hungarian: magyar korona; korona in English is "crown") was the replacement currency of the Austro-Hungarian Krone/korona amongst the boundaries of the newly created post-World War I Hungary. It suffered a serious inflation and was replaced by the pengő on 1 January 1927.

According to the Treaty of Trianon and other treaties regulating the situation of countries emerging from the ruins of the dissolved Austro-Hungarian Empire, the former banknotes had to be overstamped by the new states and - after a given transition-period - replaced by a new currency. In the case of Hungary, this currency was the korona, which replaced its Austro-Hungarian counterpart at par. Hungary was the last country to fulfil the replacement obligation of the treaties and the stamps used for overstamping were very easy to copy, so a large portion of the common currency circulated in Hungary. This was a factor contributing to the process which finally led to a serious inflation. Finally, in 1925, the korona was replaced by the pengő at a rate of 12,500 korona = 1 pengő.

The first paper money printed in Hungary were 1, 2, 25 and 200 korona banknotes - similar to those issued in Vienna during the end of the war. However, the use of these banknotes was limited to Austria and Hungary, and later even Austria considered the Hungarian issues to be counterfeits. Later, as there was no national bank in Hungary, the Postal Savings Bank received the right to print bills denominated 5, 10 and 20 korona. The overstamping of the banknotes of the Austro-Hungarian Bank started only in 1920 - the last of all states emerged on the ruins of the former Monarchy. Finally, the Hungarian Royal State Note Institute was founded and granted the right to issue treasury notes.

The Széchenyi Chain Bridge (Hungarian: Széchenyi lánchíd) is a suspension bridge that spans the River Danube between Buda and Pest, the western and eastern sides of Budapest, the capital of Hungary. Designed by the English engineer William Tierney Clark, it was the first permanent bridge across the Danube in Hungary, and was opened in 1849.

It is anchored on the Pest side of the river to Széchenyi (formerly Roosevelt) Square, adjacent to the Gresham Palace and the Hungarian Academy of Sciences, and on the Buda side to Adam Clark Square, near the Zero Kilometre Stone and the lower end of the Castle Hill Funicular, leading to Buda Castle.

The bridge has the name of István Széchenyi, a major supporter of its construction, attached to it, but is most commonly known as the Chain Bridge. At the time of its construction, it was regarded as one of the modern world's engineering wonders. It has asserted an enormous significance in the country's economic, social and cultural life, much as the Brooklyn Bridge has in New York and United States of America. Its decorations made of cast iron, and its construction, radiating calm dignity and balance, have elevated the Chain Bridge to a high stature in Europe. It became a symbol of advancement, national awakening, and the linkage between East and West.
