The Nieuwmarkt riots (Dutch: Nieuwmarktrellen), also referred to as the Amsterdam metro riots, were a series of serious disturbances in the Nieuwmarkt neighbourhood of Amsterdam, Netherlands.

On 24 March 1975, which later became known as Blue Monday,[1] and on 8 April 1975, protests against the planned demolition of homes[quantify] ended in confrontations with over a hundred municipal police supported by 500 military police.

[2] The homes were considered by residents and protesters to be in good condition, but had to make way for the construction of the East Line tunnel of the Amsterdam metro.

[citation needed] As a result of the riots, the city council of Amsterdam decided to abandon further plans for additional metro lines.

It is decorated with artworks that memorialize the turbulent times.
