In [[Europe]] during the [[Medieval]] period, [[guild]]s were formed by craftsmen to organize their trades and written contracts have survived, particularly in relation to ecclesiastical buildings. The role of architect was usually one with that of master mason, or ''Magister lathomorum'' as they are sometimes described in contemporary documents.

The major architectural undertakings were the buildings of abbeys and [[cathedral]]s. From about 900 onward, the movements of both clerics and tradesmen carried architectural knowledge across Europe, resulting in the pan-European styles Romanesque and Gothic.

Also, a significant part of the Middle Ages architectural heritage is numerous [[fortifications]] across the continent. From the Balkans to Spain, and from Malta to Estonia, these buildings represent an important part of European heritage.
