According to the Wschowa Museum, the capsule is 35 years older than the one that sits in the weather vane in Faneuil Hall in Boston, USA, dating back to 1761 and it also beats the previous earliest time capsule in Europe, which was discovered in Ziębice, Lower Silesia, in 2020 and dates back to 1797. In the 18th century, Wschowa was annexed by Prussia, and it remained part of the German Empire until the end of World War I. After the war, Wschowa was returned to Poland.
