What is Citadel?
{{no sources|date=February 2022}} [[File:Herat_citadel.png|thumb|200px|A citadel in [[Herat]].]] A '''citadel''' is a large [[fortress]] or [[castle]] that is usually built to protect [[City|cities]] or [[Town|towns]] from attacks or disaster, though citadels have been built for other reasons as well. Citadels are often built to be the final protection for a city or town, in case enemies break through other protections such as [[Wall|walls]] or [[Soldier|soldiers]]. The citadel of a city is most often built around the center of administration and government, which is where the king or city council makes their rulings. Other common places for a citadel to be placed are the [[downtown]] (central core) of the city, the [[Place of Worship|holy center]] or [[Place of Worship|religious square]] of the city (many [[Shrine|shrines]]), and the [[Central business district|business]] or [[Central business district|financial area]], where money is traded for goods, and invested. == History == === 3300 BCE - 1300BCE === === –1300 BCE === The oldest known citadels were built in the [[Indus Valley Civilization]], where the citadel may have been used as a symbol of [[authority]] (power), though no one is entirely sure why they were built. === 800–600 BCE === In [[Ancient Greece]], the [[Acropolis]] was important in the life of the people, serving as a place of safety in times of trouble. It contained [[military]] supplies, food, a [[shrine]], and often a [[palace]] or citadel. The most well-known is the [[Acropolis of Athens]], but nearly every Greek [[city-state]] had one. === 167–141 BCE === Citadels were sometimes built so strongly that enemies could take over the rest of the city, but fail to take over the city's citadel. During the [[Maccabean Revolt]], the Maccabean [[Rebellion|rebels]] managed to take over all of [[Jerusalem]] except its citadel. It wasn't until 20 years later that they finally managed to take over the citadel too. === 1600 CE–present === Citadels were not always built to keep away a city's enemi
