How to Make a Working Drawbridge for a Cardboard Castle

Create a functional cardboard drawbridge that actually lifts up and down using simple household materials.

1. Gather Your Materials. You'll need a cardboard box for your castle base, extra cardboard for the drawbridge (cereal box cardboard works perfectly), string or yarn, two small paper clips or brass fasteners, a hole punch or sharp pencil, scissors, tape, and markers or paint for decorating. Having a ruler handy will help you measure accurately.
2. Prepare the Castle Entrance. Cut a rectangular doorway in your castle that's slightly wider than your planned drawbridge. Make it tall enough that when the drawbridge is down, it covers the entire opening. The opening should be about 4 inches wide and 3 inches tall for most cardboard castles, but adjust based on your castle's size.
3. Create the Drawbridge. Cut a piece of cardboard that's the same width as your doorway opening but about 5 inches long. This extra length ensures the drawbridge will completely cover the entrance when lowered. Round the bottom corners slightly to make it look more authentic and help it move smoothly.
4. Install the Hinge System. Punch two holes along the top edge of your drawbridge, spacing them about an inch from each end. Punch matching holes just above your castle's entrance. Thread a 12-inch piece of string through each hole, then tie the ends to create loops that connect the drawbridge to the castle. The drawbridge should hang down naturally and swing freely.
5. Add the Lifting Mechanism. Punch a small hole in the center of the drawbridge's bottom edge. Thread a long piece of string (about 18 inches) through this hole and tie a knot so it won't pull through. Run this string up over the castle entrance and through a hole you'll punch in the castle wall above the door. This creates your pulley system for raising and lowering the bridge.
6. Test and Adjust. Pull gently on the string to raise the drawbridge. It should lift smoothly without catching. If it sticks, check that your holes are aligned and the string moves freely. Adjust the string length so the bridge closes completely when raised and lies flat when lowered. Tie the end of the lifting string to a small cardboard tab for easy gripping.
7. Decorate and Finish. Paint or color your drawbridge to match your castle. Add details like wooden plank lines, metal studs, or a coat of arms. You can also create a small moat from blue paper or fabric underneath the drawbridge to complete the medieval effect.
