Civil technologies

In the following, a list of some important medieval technology. The approximate date or first mention of a technology in Medieval Europe is given. Technologies were often a matter of cultural exchange and date and place of first inventions are not listed here (see main links for a more complete history of each).

Agriculture

Heavy plough
Plough
The plough or plow is a tool used in farming for initial cultivation of soil in preparation for sowing seed or planting. It has been a basic instrument for most of recorded history, and represents one of the major advances in agriculture...

(5th->8th)

The heavy wheeled plough with a mouldboard first appears in the 5th century in Slavic lands, is then introduced into Northern Italy (the Po Valley) and by the 8th century it was used in the Rhineland. Essential in the efficient use of the rich, heavy, often wet soils of Northern Europe, its use allowed the area's forests and swamps to be brought under cultivation.

Hops
Hops
Hops are the female flower clusters , of a hop species, Humulus lupulus. They are used primarily as a flavoring and stability agent in beer, to which they impart a bitter, tangy flavor, though hops are also used for various purposes in other beverages and herbal medicine...

Architecture and construction

Artesian well (1126)

Stationary harbor crane (1244)

Stationary harbor cranes are considered a new development of the Middle Ages, its earliest use being documented for Utrecht in 1244. The typical harbor crane was a pivoting structure equipped with double treadwheels. There were two types: wooden gantry cranes pivoting on a central vertical axle and stone tower cranes which housed the windlass and treadwheels with only jib arm and roof rotating. These cranes were placed docksides for the loading and unloading of cargo where they replaced or complemented older lifting methods like see-saw
