The Maharishi commune in the Limburg village of Vlodrop faces fines of up to €10,000 a time for breaking building regulations on its estate, NOS tv reports on Tuesday.
The former convent occupied by the transcendental meditation group was raided by building inspectors last autumn, who found 13 infringements.
Now the council says 164 flagpoles surrounding the convent have to be removed, numerous floodlights taken out of the woods, and illegal sleeping quarters demolished.
Maharishi Mahesh Yogi lived in the Netherlands from 1990 until his death in February this year.
