In the following year, the accident led to significant changes in safety procedures in order to avoid similar situations – not just at Roskilde Festival, but also at other festivals in Europe. Before the accident in 2000, Roskilde Festival was considered one of the safest festivals. Many other festivals have smaller safety systems than Roskilde Festival and revised their procedures even further. Glastonbury Festival in England chose to cancel its festival in 2001, in part to consider lessons from Roskilde, although mainly due to an influx of 150,000 non-ticketed visitors at its own 2000 event . Each year Roskilde Festival makes an extensive health and safety assessment on the basis of which the festival is executed. The accident at the Orange Stage led to the construction of a memorial ground on the festival site containing a stone with the inscription "How fragile we are" (a quote from the Sting song "Fragile") surrounded by nine trees.
