Physics in World Heritage

The GPWH is characterized by its interdisciplinary and multidisciplinary dimension, intending to promote the cooperation of researchers from various faculties of UC and other universities, allowing the development of scientific studies on rich primary fonts of the History of Science in Portugal. The Working Group collaborates with the UC, which is an UNESCO World Heritage site, studying the History of Science in Coimbra and contributing to the rehabilitation of buildings and equipments.
