A Monument of History is one of the four forms of monument protection listed in the Act on the Protection and Care of Monuments of 2003. This term is used to describe an immovable monument of special significance to the culture of our country. The rank of a Monument of History is emphasized by the fact that it is established by the President of the Republic of Poland by a special regulation at the request of the Minister of Culture and National Heritage. The striped flint mines from the Neolithic period in Krzemionki were recognized as a Monument of History by the order of the President of the Republic of Poland, Lech Wałęsa, on September 8, 1994.

Several facts determined the granting of the status of a Monument of History to this place:
- State of preservation, “Krzemionki” is the largest and best-preserved facility associated with prehistoric mining in the world. The mines stand out in size and cognitive value from other such facilities in the world, primarily due to the scope and nature of archaeological research and innovative conservation solutions. “Krzemionki” significantly surpasses mines such as Grime’s Graves (England), Le Grand Pressigny (France), Rijckholt-St. Geertruid (Netherlands), and Spiennes (Belgium) in this respect. The “Krzemionki” flint mining complex was discovered in 1922. Because the mine area was covered with forest, the original terrain relief shaped by mining has been perfectly preserved to this day. The establishment of a reserve protected the facility from devastation, and systematically conducted archaeological research has allowed us to enrich our knowledge of mining technology and economy in prehistory. Scientific studies conducted in „Krzemionki” are an inspiration and indication of specific research methods for archaeologists throughout Europe.
- Unique on a global scale, “Krzemionki” is a unique complex, illustrating the knowledge and technical abilities of people living in the Stone Age. Thanks to the archaeological research conducted in „Krzemionki,” we can recreate prehistoric mining techniques, the organization of mining works, and the complex systems of management of the valuable raw material that was striped flint.
- The largest range of flint deposits exploited in “Krzemionki” in the period 3000–1800 BC were of great importance to the people living in Central Europe at that time. This is evidenced by the finds of axes made of striped flint from „Krzemionki,” which reached the territories of the present Czech Republic, Slovakia, Ukraine, Lithuania, and Germany (i.e., within a radius of approx. 600 km from the deposits).
- Tourist and educational attractions: “„Krzemionki” is the world’s largest tourist site that shows the methods of exploiting flint deposits. It therefore plays a huge educational role.
