Five-time world champion Joey Dunlop was killed in an accident on the Kloostrimetsa circuit in 2000. A memorial stone was erected a year later. In 3 June 2006, the track was closed for racing after the 2006 annual Kalevi Suursõit motorcycle race as in order to bring the safety up to acceptable levels, hundreds of trees along the track would be needed to be felled, all of which are under protection as part of the park surrounding the track.[4]
