Final answer:
In medieval Europe, the center of each feudal territory was the lord's castle or manorial house, which was surrounded by lands worked by peasants or serfs.
Step-by-step explanation:
At the center of each feudal territory was typically a lord's castle or manorial house, which served as the administrative hub and the stronghold of the lord who owned the land and provided protection to the surrounding community.
The social structure was hierarchical, with the nobility (lords) granting lands called fiefs to their vassals in exchange for military and other services.
The feudal system, deeply intertwined with the Catholic Church, ensured that power was maintained through a complex series of oaths of loyalty, with the peasants or serfs working the land to support this framework.
