[1] Amsterdam's first commodities exchange was built in 1608-1609 at the corner of the Rokin and Dam Square.

The commodities exchange, designed by Hendrick de Keyser, played a key part in the economic success of the city during the Dutch Golden Age.

The archeological finds in what used to be the Amstel river are expected to shed new light on the history of Amsterdam and on the landscape and environment of the area in the millennia that preceded the founding of the city.

[2][3] The Mirakelkolom, which normally stands on the Rokin, was temporarily removed during the construction of the metro line.

The Mirakelkolom is a stone column made up of remnants of the Heilige Stede (Nieuwezijds Kapel), a chapel built to commemorate the 1345 Mirakel van Amsterdam (Miracle of the Host).
