The Weapon Repair Shop is located beneath a guardhouse on the castle wall. Knights and footmen can drop in and sharpen or repair their weapons whenever necessary. The shop has a grinding wheel, an anvil, and a variety of tools.

The second floor opens to reveal the interior of the guardhouse. The guardhouse has a weapon rack and other storage. A parapet above the guardhouse helps in the defensive of the castle.

This project is built in the style of the classic LEGOŽ Castle sets of the 1980's. It is designed to fit with Black Falcon's Fortress (6074), Armor Shop (6041) and other modular castle sets of the era.
