The whole world is built around Amsterdam' wrote the famous Dutch poet Joost van den Vondel in the seventeenth century. This century - being the Dutch Golden Age - was to Amsterdam a previously unexperienced period of prosperity. People came to the city for business or a decent living. The old town area became too small, so an extension was inevitable and three new main canals were dug out: Heren-, Keizers- and Prinsen-gracht. Between them cross-canals and -streets. Our quarter of '9 Streets' was constructed in the first half of the 17th century and was from the beginning until now dominated by trade and culture. The names of the streets remind us of the old artisans dealing with all kinds of skins for the leather-industry.
