This is my knex castle that I built for a school project. It is 3' 5 1/2" (1 meter, 5 1/2 centimeters) long and 2' 8 3/4" (83 centimeters) wide and 2' 9" (84 centimeters) tall at its highest point. It is my design of a European medieval castle. It took me about 18 hours, in a span of a few days, total. We had a whole list of stuff that we had to put on our castle, but they were only mandatory in the blueprint. I put most of them on the model but not the very detailed things. It has a working drawbridge that goes over the imaginary moat and to the imaginary land around it. There is also a postern gate (a side or less important gate/bridge) on the side of the castle. There are 15 rooms and two staicases. There's a bunch of other things that I will show in the instructable if you want to know more.

The castle is made up of about 5,496 pieces.

Step 1: The Towers and Outer Walls

The towers are actually called turrets, except the large inner tower which is called a donjon.

Step 2: Stairs

The stairs are so awesome that they deserve there own step. There are two sets of staircases. There is the spiral staircase, in one of the turrets, that gives access to all three floors of the castle. There is also a small set of regular stairs that lead to the bailey, which is the courtyard.
