The second season of Foundation was filmed all over the Czech Republic – primarily in North Bohemia and Ostrava, as well as in Prague, Kladno, Sedlec, Pardubice, and Střemy. The Homolák Quarry, Prachov Rocks, Dobříš, and Kačina Chateau feature in the series. According to the Czech Film Commission, location scouts were tasked with finding brutalist architecture. Production was highly technical and sometimes complicated, featuring sets flooded with water and LED volume technology (large-scale display tech using LED lights for vivid images) and 3D printed props.
