Instructions for cardboard castles

Many children love stories about knights and castles so it stands to reason that they would also enjoy making their own cardboard play castle. With some basic supplies--cardboard, paper, and glue--it is possible to make a functional play castle that your children can have as much fun making as they do playing with it. This project provides children with the opportunity to express their creativity and to make a custom play castle that meets all of their specifications.

Cut four strips of white construction paper using the toilet paper tubes as a guide for the length of the strip. Wrap one sheet of construction paper around each tube and glue it in place.

Cut out a piece of cardboard measuring approximately 14 inches long by 5 inches tall using one of the empty cereal boxes to create the guard house. Mark the piece of cardboard at 5, 7, 12 and 14 inches, then fold the cardboard on each mark, making a firm crease on each fold. Connect the two edges of the piece of cardboard to form a rectangular box and secure the edges with a piece of tape.

Cut out a piece of cardboard measuring approximately 8 inches long by 10 inches tall using another empty cereal box to create the tower. Mark the cardboard at 2-inch intervals and make a fold on each mark, dividing the piece of cardboard into four sections measuring 2x10. Connect the two edges of the cardboard and attach them securely with a piece of tape to create a tall box.

Cut out four equal-length pieces of cardboard using the third empty cereal box to create the walls for your castle. The pieces should be 3 inches to 4 inches tall; the length will depend on how large you want your castle to be--the longer the pieces of cardboard, the more space you will have in the centre of your castle.

Cover the walls of your castle and the two cardboard boxes with white construction paper and glue it in place.

Cut out small square sections from the tops of the walls, the tower, the guardhouse, and the corner towers of your castles. These cut-out sections should be spaced evenly--alternate a 1/2 inch by 1/2 inch section of cardboard with a cut-out section of the same size.

Attach the pieces of your castle using glue and/or tape. Begin by gluing one of the corner towers down on the piece of corrugated cardboard and use a section of castle wall to connect it to a second corner tower. Cut two castle wall sections into smaller pieces and use them to connect the front two and back two corner towers to the guard house and the tall tower.

Decorate your cardboard castle by painting it grey and making bricklike markings on it. You can insert flags into the tops of your corner towers and draw in windows.


Create your own castle design by altering the measurements of the towers and guard house. Be creative when decorating your castle--add a drawbridge, a moat and any other details you desire.


Use glue sparingly; otherwise, it might take a long time to dry and your paper can become soggy and unusable.
