Archaeologists excavated in Tallinn. They found an ancient seal. The seal belongs to the pope. It is very old.
Mihkel Tammet is an archaeologist. He says this is a rare find. The seal is medieval. Other finds also indicate this.
The seal was found in black soil. Tammet believes it dates back to medieval times. The soil came from the old town. This soil was used in gardens.
Ivar Leimus is a historian. He says there are few papal letters in Estonia. The seal is the first such find.
Tammet did not immediately know what it was. He thought it was a coin. But it was a tin seal.
