Hand-made paper has been produced in Velke Losiny, North Moravia since the beginning of the 16th century. Established by the Zerotin family, the actual manufacturing site used to be a unique wooden workshop built from the remains of a flour mill. The written records state that this paper mill, which was soon followed by others, began its operation between 1592 and 1596. Other documents, such as the remains of the oldest surviving paper samples, have watermark imprints with the year 1596 and the Zerotin's family coat of arms.
