Madrid City Council member Rita Master led the protest by turning 40 olive trees donated by the Israeli Embassy into a memorial to the Palestinian victims of the Israeli genocide.
Master and other council members placed Palestinian flags and 40 memorial plaques near the trees, each telling the story of a Palestinian victim, including children, journalists, health workers and farmers.
The trees were originally donated by Israel to mark 40 years of diplomatic relations between Spain and Israel.
And the mayor of Madrid, José Luis Martínez-Almeida, accepted the "gift", which caused outrage and controversy.
The mayor of Madrid is accused of handing the city over to Israeli rule and attacking Benjamin Netanyahu's government.
Master demanded that the site become a space to condemn genocide and honor the Palestinian people, and called for its name to be officially changed to the "Olive Grove of the Palestinian People".
