A castle is a type of fortified structure that was commonly built in mediaeval Europe. Castles were typically built for defensive purposes, with high walls, thick stone structures, and often a moat surrounding the perimeter.

Castles were used as the residences of the nobility and were also used as military strongholds. They often contained barracks, armouries, and other facilities that were used by soldiers to defend against attackers.

The design and architecture of castles varied depending on the location, time period, and purpose for which they were built. Some castles were designed primarily for defence, with high walls and narrow passageways that were difficult for attackers to breach. Others were built for luxury and comfort, with spacious living quarters, elaborate gardens, and other amenities.

In addition to their practical functions, castles have also played an important role in art, literature, and popular culture. They have been depicted in countless works of literature, including fairy tales, fantasy novels, and historical fiction.

Today, many castles have been preserved and serve as popular tourist attractions, drawing visitors from all over the world. They offer a glimpse into a bygone era and provide a fascinating window into the history of mediaeval Europe.

While the use of castles as defensive structures declined over time, their legacy continues to live on. Castles have come to symbolise strength, resilience, and endurance, and they remain an enduring part of European history and culture.
