Some examples of the vandalism that has occurred:
1964 - Danish artist Jørgen Nash and and his former comrades from the Situationist International (Nash had been excluded from the society after being caught trying to “conspire” with certain art dealers). Nash and friends decapitated the statue and the head was never found. A new head was cast and attached. Nash claimed the vandalism was his stand against the consumerist society.
1984 - The right arm was cut off (on the left in this photo). 2 days later it was returned by the remorseful vandals.
1990 - A second attempt was made to cut the head off. This time it was unsuccessful but an 18 cm (7 inch) cut was left in the neck.
1998 - The head was cut off for a second time. The culprits were never identified but the head was returned anonymously to a local TV station and was reattached.
2003 - Vandals used dynamite to blast the whole statue off its rock.
2006 - Feminists poured green paint over the sculpture, attached a dildo to the hand, and wrote March 8 on the mermaid. March 8 was International Women’s Day.
2007 (March) - The Little Mermaid was painted pink.
2007 (May) - It was painted again
2007 (Later in May) - It was found dressed in a burqa, the second time this has occurred.
