For centuries, the life of Salgótarján and its region has been determined by industry, including coal and stone mining and mechanical and glass production, which have been mostly closed down and eliminated. Based on these extremely strong traditions, some of the sloped pits of Joseph, located in the central part of the city, were adapted for museum presentation. Hungary’s first underground mining museum was opened in 1965, which is still a rare museum in Europe. The Mining Museum, which operates with virtually unchanged content, has been one of the city’s popular cultural and tourist destinations for decades and attracts thousands of visitors to this day. One of the most popular sights in Salgótarján attracts several target groups, in addition to primary and secondary groups, many tourists with boots enter the Mining Museum. In addition, the museum is an important destination for retired groups, tourists from home and abroad, families with young children. However, the rare spectacle is now very outdated and cannot meet the needs of today’s visitors. In our fast-paced world, a traditional collection attracts only a fraction of the visitors, and influenceability and teaching also affect younger age groups. The current museum is divided into three parts: the underground area, the external display site and the inner exhibition. With the greatest attraction of these, the exhibition in the underground area is undoubtedly the most significant attraction. In this part of the museum ensemble visitors can benefit from the experiences of the mining walk. In the underground mining system today museum machines, the cutting network, the portal, the inlet section, the sloping conveyor, the aircut in most of the original states represent the coal mining in the county in the 19-20th century. The inner exhibition follows decades of earlier exhibition trends, mining traditions, the history of Salgótarján mining, the life of miners are presented with the help of classical presentations, i.e. exhibitions, tableboards, maps, puppets and displays. In the exhibition, the miner’s festive costumes, accessories, contemporary tools, lighting tools, storage and accelerators, plant recordings, statistics and documents make the development of mining in the county understandable. In the courtyard of the exhibition hall, the skanzen was built, where locomotives, glitters and transport wagons are located. On three narrow-gauge railway lines, the use of traversable means of transport can be interpreted by a map placed on the wall of the building. Visitors must also have decisive, tangible experiences, in addition to having valuable “treasures” in a museum. Interactivity is now essential. In view of the current demographic and tourism data, it is imperative to have new attractions unique in the area, which, thanks to their higher added value, meet the expectations of today’s society and are able to increase the number of guest nights in the region. Accordingly, we intend to implement an interactive children’s museum in the neighbourhood of the Mining Museum, which uses the toolkit of informal experience-based learning in addition to being extremely popular and contributing fundamentally to young people’s awareness-raising and experience-building. The main focus of their activities is the support of learning through discovery, play and, of course, entertainment. Through its special target audience, it represents a very new colour, both from a cultural and educational point of view, and is able to achieve the above objectives. The Children’s Museums are today extremely popular, due to the fact that, in advanced societies, an adult is a highly qualified generation who, with special care, is looking for more and more demanding leisure programs for their children. In addition to clearly building on the history and mining traditions of Salgótarján and its surroundings, the planned children’s museum in Salgótarján highlights coal and puts it into a whole new light. A large number of children’s museums in the world have their own characteristics to provide their visitors with the most general knowledge of their target group, the age group of 3-12 years. Coal, however, as one of the most common elements in the world, provides an opportunity for the specific transmission of this general knowledge. In other words, not only as a fuel obtained from mining, but also as a physiological or chemical element, or as a raw material for commercial products, or as a fuel used in transport, may also be present in the interactive exhibition. In Hungary, the Children’s Museums have not yet been established, but it is increasingly popular in Europe. The most common feature in Hungary is that existing museums open children’s corners and rooms designed for children. However, this form is not widespread, and there is no children’s museum similar to Western Europeans. This museum form is available next to Vienna (Schönbrunn Kindermuseum, ZOOM Kindermuseum).
