The Tøjhusmuseet is a fascinating museum for anyone interested in military history. Inside is a huge collection of arms, weapons, vehicles, aircraft, uniforms and informative exhibits. The displays trace war events since the Middle Ages. Although the Tøjhus Museum was established in 1928, it is housed in the former armory of King Christian IV. When the arsenal was built in 1604, the massive width of 534 feet made the structure the largest armament in the world.
