While fortifications and stately homes have been known since ancient times, the combination of those functions arose in Europe around AD 900, as strongholds of local feudal lords, to hold off enemy raids by Vikings, Magyars, Saracens and nomads, as well as rival lords.
The rise of castles is usually held as the transition from the Early Middle Ages to the High Middle Ages; periodization is however a construction of the afterworld, and no specific year can be pointed out as the "year zero" of castle construction. While knights, men of noble birth, skilled in warfare from horseback, had been around since the 8th century, they became organized in religious orders, who usually had castles built.
Castles went through many stages of development, to respond to military and economic needs. They were usually built on high ground, to improve their role of defense, as well as their role for observation and prestige. A castle was usually the dominant building of a town, only contested by the church.
The adoption of gunpowder weapons from the 14th to the 17th centuries made castles gradually less useful as fortifications, and replaced by bastion forts. The style with towers and battlements remained for decoration of palaces and grand houses well into the 19th century, and can still be seen in novelty architecture.
Three Gothic castles, strategically positioned so as to allow fire signalling between each other, adorn the Kyrenia Mountains. They were built (or re-built) by the Lusignans, a royal family of French origin, who established a kingdom on the island facing the Holy Land during the Third Crusade.
- 1 St Hilarion Castle (south of Kyrenia, off the highway to Nicosia). The best preserved and most easily accessible of the trio. Some say it is the inspiration behind Disney's Sleeping Beauty.
- 2 Buffavento Castle (east of Kyrenia, near Çataköy). On a lofty position, this is the highest of the mountain castles of Cyprus—and it's little wonder its name means "the challenger of the winds" in Italian.
- 3 Kantara Castle (at the base of the Karpaz Peninsula). Kantara lies east of the other two, and affords commanding views over the Karpas Peninsula, the long, finger-like cape of Cyprus extending towards the Levant.
- 4 Český Krumlov Castle, Zámek 59, 381 01 Český Krumlov. Home to a Baroque theatre, which is the only one in Europe that has survived in its original 18th-century configuration with no modern additions.

- 9 Château de Pierrefonds, Pierrefonds, ☏ . A castle dating back to the 12th century, though it was renovated in the 19th century. Nevertheless, many of the original fortifications survive. Commonly used as a filming location for television series set in medieval times, perhaps most notably the BBC television series Merlin.
Germany has an abundance of castles as the medieval period saw a vast amount of small and tiny polities gaining de facto independence and there were several low ranking noblemen who had their own castle as a defense in case of (frequent) feuds or a safe haven from which to strike trade routes and the likes. The 13th century with the almost total collapse of central authority in the Holy Roman Empire saw a high point in feuding but even after feuds were largely eliminated and legal recourse for disputes was established new castles were constructed for various defensive and - increasingly - representative purposes.

- 11 Burgruine Streitburg, Wiesenttal, Forchheim, Upper Franconia. This ruined castle is on a hill right next to the hill Neideck stands on (see below) "Streit" means "quarrel" in German and the tale goes that the two neighboring castles had a quarrel with each other leading to the destruction of both. The actual history doesn't confirm that tale but locals like to tell it regardless.
- 12 Burgruine Neideck, Wiesenttal, Forchheim, Upper Franconia. Next to Streitburg on a neighboring hill, this castle ("Neid" means envy) is said to have fallen victim to the same quarrel as Streitburg although, again, the actual history was different.
- 13 Nuremberg Castle. Dating in its earliest parts to around the year 1000, this castle was at times an important residence for the Emperor when he traveled around his realm. Later the castle became a major symbol of the independent Freie Reichsstadt that was only subject to the emperor (and that only in theory) and it remains to this day a symbol of the largest city in Franconia. As the former lords of this castle were the ancestors of German Kaisers Wilhelm I and Wilhelm II they liked to make some Romantic gesture harkening back to the origins of their house and trying to link their Reich to that of which Nuremberg had once been part. The later decision of the Nazis to hold their big rallies in Nuremberg was later also linked to Nuremberg's imperial history.
Italy was comprised of numerous city-states and small kingdoms from the fall of the Roman Empire until its reunification in the 19th century, many of which were frequently at war with each other, and numerous castles were built to protect the leaders of these small states.

True Castles (those built for defensive purposes) in the United Kingdom were constructed from the start of Norman Conquest onward, until the early 17th century when developments in military technology rendered them less effective from a defensive viewpoint. Sometimes the castles were built on or near the basis of early pre-Norman fortifications.

- Main article: Japanese castles
While different in style from their European counterparts, Japan was also a nation of castle builders during the feudal period from the start of the Kamakura Period (12th century) to the end of the Azuchi-Momoyama Period (17th century). Unlike most surviving European castles, the main keeps (天守閣 tenshukaku) of Japanese castles were largely made of wood, so many have either decomposed or been lost to fire over the years. In addition, unlike in Europe, the main keep of the castle was a purely military structure and not the lord's residence, and there was typically a separate set of palace buildings next to the main keep to serve that purpose.

Not classified as an original castle as the main keep was burnt down in a fire in 1750, but the outer fortifications and main palace buildings survive. Famous for its "nightingale floors", which were deliberately designed to squeak when someone walks on them so the Shogun and his guards could be alerted to any potential assassins.
