A rolled-up piece of paper used to stop drafts in a wooden floor is actually a document dating from 1771 listing how much money officials planned to give a Dutch princess, website nu.nl reports on Wednesday.

According to archivists, the list from the seven provinces that made up the Dutch republic, was compiled for the christening of princess Louise, one of the daughters of Willem V of Oranje-Nassau, the republic’s last stadhouder or leader.
In total, the provinces collected 36,300 guilders for the princess and also paid for maternity nurses and other help, according to the nu.nl report.
Other pieces of paper found stuffed in the floor of the house in Amersfoort included documents from 1739 relating to a murder and a will. All the documents will go on show in the Amersfoort official archive in March.
