On May 5, 2022, the Museum of Light Village hosted the VIII Colloquium of of the Rural Museums Network of the South. A day with very interesting communications that sought to carry out an unprecedented exercise: comparing three Portuguese villages that were submerged by artificial reservoirs. Three villages that tell of their historical exceptionality through museums or interpretive centers. In this case, the Museum of Light Village, the Ethnographic Museum of Small Village of Cave and the Interpretive Center of Village of Beech.
