Understanding Medieval Arms and Armour
Medieval armour is not a static object but the product of an ongoing arms race between attack and defence. Each new weapon forced a new form of protection; each new protection provoked a new tactic. The result is an evolutionary history spanning five hundred years. Find castles with the best armour collections on the map.
Mail: Early Medieval through the 12th century
The hauberk of interlinked iron rings was the standard armour of the early medieval warrior. It protected against cutting blows but was less effective against thrusts and against blunt weapons such as maces and axes. A good mail shirt contained tens of thousands of individual rings, each hand-linked; a smith required months to complete a finished piece.
Plate elements in the 13th century
From the early 13th century, individual elements of hardened steel were riveted onto mail or worn underneath it: knee pieces (poleyns), elbow pieces (couters), shoulder defences. This hybrid transitional style is well documented on the effigy figures on medieval tomb monuments, such as those at Canterbury Cathedral.
Full plate: 14th to 15th century
Full plate armour — individually formed and fitted steel plates for every part of the body — emerged in the 14th century and reached its technical perfection in the late 15th and early 16th. A good Gothic plate harness of 1480-1510 was lighter than many modern military loadouts: 20 to 25 kilograms, distributed over the entire body. A well-equipped knight could run, jump, and fight in it.
The plate dilemma: lance and crossbow bolt
Plate armour was largely effective against the sword — but increasingly vulnerable to crossbow bolts at close range. Late 15th-century armours have characteristic dimples or indentations: armour "proofing." The curved surface was meant to deflect the bolt; armours were test-fired by gunsmiths, and the visible indentation (proof-mark) served as a quality certificate.
Swords, lances, and spears
The sword was a status symbol and secondary weapon; the primary weapon in mounted combat was the lance. The knightly ideal of the single combat encounter — two riders, two lances — has little to do with the real medieval battlefield, on which footsoldiers with longbows, crossbows, halberds, and pikes generally decided the outcome.
Collections in castle settings
The most significant armour collections in castle contexts include Schloss Ambras at Innsbruck, the Tower of London, the Château de Pierrefonds, and Churburg Castle in South Tyrol — one of the most complete private collections of authentic medieval armour anywhere.
Forgeries and restorations
Many museum armours are restorations or composites assembled from parts of different origins. Provenance is decisive: an armour from Churburg, in the same family residence for centuries, is more authentic than an auction piece of unclear origin.
