What is castle in chinese?

城堡（chéng bǎo）is the Chinese term for castle. Castles, or fortresses, were built in China during the Warring States period (475-221 BC) to defend against attacks from rival states. The castle architecture in China was heavily influenced by the military strategies and technologies of that time, such as the use of crossbows and chariots.

Notable Chinese castles include the Forbidden City in Beijing, The Great Wall of China, and the magnificent Terracotta Army in Xi'an. The Forbidden City served as the imperial palace and center of power for Chinese emperors during the Ming and Qing dynasties. The Great Wall of China has always been a symbol of greatness and strength of the Chinese people.

Castles in China were typically built using brick, wood, and stone, and designed with thick walls and towers to withstand sieges. Castles were also surrounded by moats and barbed wire, further fortifying their defenses.

Today, many Chinese castles have been restored and renovated, and their grandeur and magnificence attract visitors from all over the world.
