The King is paying a visit to the cellar, where all his supplies of beer and brandy are stored. The palace complex includes a brewery. The beer, known as 'Königlieblingbrau' is brought to the large cellar for lagering then put into smaller barrels to move it to the kitchens or offsite to other royal residences.
I hadn't planned to do the cellar, but I got the idea when I saw the large plastic barrels at a local 'car boot' sale. A nice simple room to construct, the walls and floor are printed paper stone and flagstone sheets, the doorframe is a made from cardboard with the door from a scanned in image of part of a old model railway building; the large table is a piece of dolls house furniture with the legs cut down.
