Demand of Dutch merchants for a mark in the Gulf of Tallinn, 1470

This demand was submitted by some Dutch traders to the town council of Talinn in 1470. They wanted a seamark to be placed in the Gulf of Tallinn halfway between the islands of Paljassaar and Naissaar to mark the approximate position of a dangerous reef. A buoy from Lübeck was installed for the huge amount of 156 marks and 12 killings. Its maintenance was covered by an additional duty, "tun money", levied on all ingoing vessels and recorded since August 1471. This seamark is depicted on the first detailed Dutch sea chart of the region, published by Lucas Janszon Waghenaer).
