The Rokin is a water and street in Amsterdam, located between the Muntplein and the Dam, where the last stretch of the Amstel used to be.
The oldest records of the name Rokin date from 1559 (as Ruck-in), 1563 (Rock Inne) and 1564 ('t Rockin). The name indicated the quay that had been constructed shortly before on the west side of what was then Amstel, just south of Dam Square. To do this, the buildings that had been up to the water of the Amstel had to 'push in'. There is no historical evidence for the well-known story that Rokin is a corruption of Rak-in. Rak is the name for a straight section, but nowhere in the Netherlands that word has been changed into a skirt and no preposition or adverb is ever pasted behind it. The water has only sometimes been called Rokin since the seventeenth century.
