CHARME Project Rubble Wall Masonry
The method of construction for the walls of the Hundisberg castle garden was "Rubble Wall" masonry. In this technique first the walls are built up to the course line, then the interior is filled with a mortar bed, then all irregular stones are placed in the mortar bed, and it is built up to the level of the outer shell of the wall. When the level is finished, a thin coat of mortar is brushed over the top of the level to provide a clean surface for the next course to be laid on top.
