Nieuwmarkt has an island platform of 165 metres (541 ft) and two halls with a total of three entrances and was opened to the public on 11 October 1980.

The station was designed by two architects from the Government of Amsterdam: Ben Spangberg and Sier van Rhijn [nl].

[9] This was not a big problem at Weesperplein and Wibautstraat, but at Waterlooplein and Nieuwmarkt, the tunnels had to run through the old Binnenstad of Amsterdam, causing the demolition of several housing blocks.

[10] The destruction of houses above Nieuwmarkt started in December 1974 and was met with protests, which eventually resulted with the cancellation of all other planned metro lines.

[11] Construction on the tunnel section from Zuiderkerk to Amsterdam Centraal, which includes Nieuwmarkt station, started in the summer of 1975.

When operations restarted, the residents living above the section between the Prins Hendrikkade and Stopera complained of vibrations when a metro was passing by.

[13] In April 2017, the GVB started to play music through the speakers of underground metro stations as a test.

[17] Artists were invited by officials for artwork inside the stations on the East Line, with the exception of Weesperplein and Bijlmer.

[18] The five artworks at the station form a collective work where the artists express the history of the Nieuwmarkt neighbourhood.

[21] Scheuren en gaten in de wanden of Bert Griepink consists of half demolished walls, parts of wooden fences and large photos scattered all over the station showing the demolition of Nieuwmarkt and the last cries of resistance.

[23] Groeten uit de Nieuwmarkt was created together by all three artists and Roel van den Ende and consists of four triptychs in total.

[24] The fifth artwork, Wonen is geen gunst maar een recht by Tine Hofman, was added to the station in 1997.

[25] In 2012, it was announced that the wrecking ball and the photo collage, as well as a few other artworks in different stations, were planned to be removed during the upcoming renovation as they were damaged.
