Matěj Hájek is a Czech artist. He graduated from the Academy of Fine Arts in Prague, where he specialized in sculpture under the guidance of Jaroslav Róna. His creative work blurs the boundaries between architecture, sculpture, and land art. He has long been exploring the relationship between sculpture, play, and learning, which is reflected in large-scale children's playground projects. In 2021, he was invited by the chief curator of the Venice Architecture Biennale to create an installation titled "OFF FENCE / PLOT." Projects he has contributed to have received awards such as the Grand Prix of Architects, Timber Building of the Year, and a nomination for Czech Grand Design. Since October 2019, he has been continuing his doctoral studies at his alma mater, the Academy of Fine Arts.
