In The Netherlands (and many other places in Europe) graves are leased, and old graves can be removed after the lease has expired to make room for new ones (you can read more about this practice in the latest edition of the Trace your Dutch roots newsletter). When the cemetery plans to remove a grave they will contact the family to invite them to extend the lease on the grave. If they can’t reach the family’s contact person, they will put up a notice at the notice board at the entrance, and place a sign at the grave, stating the grave is about to be removed.
This is the grave of Johannes du Saar and Elisabeth du Saar-Pasveer, at the Tolsteeg cemetery in Utrecht. In front of the grave there is a little sign asking the family’s contact person to contact the cemetery administration. This grave will probably be removed soon.
Patricia’s grave is at the Noorderveld cemetery in Nieuwegein. The green sign states that the grave is on the list of graves to be removed in early 2009 (the photo is from November 2008). Interested parties should call the phone number provided to extend the lease.
I did not check if the grave is indeed removed.
The grave of Rob and Moeder (Mother) is at the Onze Lieve Vrouwe cemetery in Amersfoort. The red sign reads Dit graf wordt geruimd, this grave will be removed.
