Become a virtual archaeologist with Heritage Quest

The Luxembourg National Institute for Archaeological Research (INRA) has launched an international research project called Heritage Quest. The initiative invites members of the public to help search for hidden historical monuments using LiDAR (Light Detection and Ranging) technology. As explained by Maxime Brami, a professor at Johannes Gutenberg University in Mainz, this method is based on the emission of laser pulses from aircraft. The reflected signals form a detailed 3D map of the terrain, allowing even the slightest changes in the relief to be recorded and hidden structures to be identified, even through dense foliage.

At the same time, volunteers do not need any specialist knowledge to take part in the study. Image analysis is carried out via a dedicated online platform using a smartphone or computer, where users are provided with the necessary instructions and examples of the objects they are looking for. Brami emphasised that the chances of discovering previously unknown archaeological remains are very high. In particular, a similar system in the Netherlands has already enabled citizens to identify thousands of new historical sites. In Luxembourg, the initiative, which is set to run for the next three years, is aimed not only at finding new sites but also at protecting existing monuments in forested areas.

The launch of the Heritage Quest project coincided with the start of European Archaeology Days, which will run until 19 June. As part of this programme, according to Culture Minister Eric Thill, 15 educational events have been organised in Luxembourg, including guided tours, workshops and exhibitions of archaeological finds. This international initiative, aimed at strengthening interaction between researchers and the public, is taking place for the fifteenth time and covers more than 30 European countries, although this is only the second year of participation for Luxembourg.
