The first organisation to provide security for Prague Castle after the establishment of the independent Czechoslovak Republic on 28 October 1918 was the Czech Sokol Community. On 6 December 1918, by order of the Headquarters of the Czechoslovak Armed Forces, an infantry company was established for the protection of Prague Castle, which fell under the jurisdiction of the 28th Infantry Regiment in Prague. In May 1929, historicizing uniforms based on the uniforms of the Czechoslovak legions in France, Italy and Russia were introduced to the Castle Guard. After the occupation of the republic by German troops on 15 March 1939, the 1st Battalion of the Government Army of the Protectorate of Bohemia and Moravia took over its tasks. However, the direct legal continuity of the Castle Guard was maintained by the guard group of the President of the Republic in exile in Great Britain. Between 1945 and 1948, the Castle Guard was again built according to the model used during the years of the First Republic. During the communist regime, the Castle Guard lost its elite character and became a token unit of the Ministry of the Interior. The events of 17 November 1989 and the subsequent socio-political changes brought the Castle Guard completely new tasks and status. Nowadays, the Castle Guard is an independent part of the Czech Armed Forces and worthily follows the tradition of the Czechoslovak Legions.

The exhibition is organized by Prague Castle Administration, Military History Institute Prague and the Castle Guard. 

Mihulka Tower

The Mihulka tower was built in the second half of the 15th century as the most massive cannon tower of the Prague Castle fortification according to the plan of the builder Benedikt Rejt. In addition to its defensive tasks, it had many other uses in its history. In the second half of the 16th century, the bell-ringer and cannon maker Tomáš Jaroš from Brno had his workshop in the tower. During the reign of Rudolf II, Mihulka was roofed and used as a dwelling for the castle alchemists. During the Thirty Years' War, the tower was turned into a powder magazine. It was then used as a powder magazine until 1754, and over the years its second name, the Powder Tower, was adopted.
