The Reformation Wall in Geneva, Switzerland was vandalised in mid-July with multi-coloured paint thrown onto it from above.
The monument is one of the main tourist attractions of the city in which John Calvin, one of the key French Protestant Reformers, developed his work after 1536. The wall, inaugurated in 1909, also honours the influence of Guillaume Farel, Théodore Beza and John Knox.
Rainbow?
Reports suggest that the paint deliberately forms a rainbow, a symbol of LGBT groups. An LGBT pride march took place in Geneva the previous week. Around 35,000 people passed through Bastions Park close to the Old Town, where the monument is located. But the police have said that no-one has claimed the attack.
Geneva city council will file a criminal complaint and staff said the monument would be cleaned as soon as possible.
According to a Swiss journalist, the clean-up would require the intervention of two men, full time for seven days, with a cost of 13,000 Swiss francs (£10,788).
There have been a number of acts by vandals against the Protestant monument in the past. According to newspaper Le Matin, in March, feminist activists wrote graffiti on the wall reading: “Where are the women?”
