A documentary film on the a four-tonne glass object for the sarcophagus for Margrethe II, Queen of Denmark, which Czech glassmaker Zdenek Lhotsky was making for five years, was shown to the public for the first time in the Prague Museum of Decorative Arts earlier this week. The film is the only possibility to see the sarcophagus, which was installed in the crypt of the Roskilde Cathedral in April 2018.
