The Tolprivilege is a document that dates from October 27, 1275. In it, Earl Floris V gives the inhabitants of 'Amestelledamme' the right to transport their goods through the then existing County of Holland.
Its historic significance lies in the fact that this is the oldest known document that mentions the name of Amsterdam. Therefore, the date of October 27 (the date of the document) is now used to celebrate the 'birthday' of Amsterdam. Every year around October 27, the Tolprivilege is shown to the public for a few days, in the Stadsarchief (City Archives).
