In the 16th century a row of buildings stood on the west side of the palace yard, including the houses of the Canons, the bread distribution house and the bakery, as well as a large granary. Only the cellar situated under the row of houses survives to this day

The outer and inner castle system was developed in the 1540s. The passage between them was the Dark Gate which is still visible today. The outer castle was destroyed in 1702, but the gate continued to be used and was only walled up at the beginning of the 19th century.

Heroes' Hall, situated on the ground floor of the Bishop’s Palace, commemorates the greatest figures of Eger Castle. The red marble cover of István Dobó’s tombstone, depicting the heroic commander dressed in battle armour, was brought here in 1965.

The exhibition presents archeological findings from the territory of Heves County, from the Stone Age to the era of the Hungarian conquest of the Carpathian Basin. The exhibition provides an insight into the work of archeologists and restorers from the beginning of the collection to the results of the latest research, as they attempt to put together pieces of our history from the objects and phenomena discovered.

The Eger Bishopric was founded by Saint Stephen between 1001 and 1009. The Cathedral, consecrated in the name of Saint John, was built on the castle hill during the 11th and 12th centuries and became the final resting place of, among others, King Emerich I.

Chronologically and geographically, the collection covers a wide range of weapons from the Middle Ages to the World War I, from Europe to Africa and the Middle East. In addition to the Ottoman weapons and the contemporary Hungarian arms, that form the backbone of the collection, the exhibition also seeks to interpret the development of weaponry and the revolutionary impact of gunpowder.
