Moeschal studied architecture at the Academy of Fine Arts in Brussels, afterwards he took a sculpting course. With a modern approach of a changing world, he was inspired by sources from the past (prehistory, Egypt and the Middle Ages). He was mainly focused on the monumental sculptures and on the integration of works of art in a public space. He followed the developments of science and the technical possibilities new materials gave him. He worked with concrete, aluminum or cortex steel, which were especially fit for his pure and rhythmic shapes. He worked closely with engineers and often shifted his technical borders. The symbolic sculptures of Moeschal arise as signs on symbolic places where they have a dialogue with the space.
