This castle just north of the small town of Ystad, Sweden has been used as a training facility for the Allback window restoration school because it had a large number of windows, interior and exterior details that had been painted with petroleum oil and acrylic paint for a long time. This had caused serious deterioration.

A number of windows and the chapel has been restored by the with the Allback linseed oil paint and the Allback interior paint as well. The last photo shows the terrible condition of a window in bad need of restoration on the same castle and is on the list of the Allback method. The complete character of the old windows was maintained in the restoration process.
