The castle was originally built as  a tower house, but has been later expanded into a proper fortification. In the areas where the walls don't reach, the steep cliff is the main form of defense. Round towers, reaching out from the line of the wall, provide more angles of fire around the castle.

The gatehouses form a major part of the castle's defenses, turning the enemy into a static target.

Maintaining a castle requires constant work, for which workers from the nearby village are called for.

The windows higher in the building are bigger to let in more light, while not negatively affecting the defensive properties.

As the castle expands, older parts are changed to integrate well with the new areas.

Layered design allows for multiple uses for individual elements.
