A dzong is a type of fortress or monastery found primarily in Bhutan and Tibet. These impressive structures serve as administrative centers and religious institutions, showcasing traditional Bhutanese architecture. Dzongs are characterized by their massive walls, intricate woodwork, and beautiful paintings, often situated on hilltops or near rivers for strategic defense. Historically, dzongs played a crucial role in unifying Bhutan and protecting it from invasions. Today, they continue to be important cultural symbols and are used for various festivals and ceremonies. Many dzongs, such as the famous Paro Dzong, attract tourists and serve as a testament to the region's rich heritage.
