The goal of the portal ‘Prague – the City of Archaeology‘ is to make the archaeological sources of Prague available to professionals as well as the wider public. It shall facilitate the archaeologists and their collaborators to be able to systematically study the past and to embrace it in a faster and broader way. Through this portal, the wider public has a chance to visit Prague underneath Prague, tracing its past and sharing the excitement of exploration of the unknown. Moreover, they can discover the impeccability of forgotten technologies and handicrafts or learn about endless possibilities of various topics that archaeology offers. The Praha-archeologicka.eu portal is the main outcome of the project ‘Integrate Information System of Archaeological Sources of Prague (IIS_APP)’ which is the common project of the Institute of Archaeology of the Czech Academy of Sciences (CAS), Prague, v.v.i. and the National Heritage Institute.
