Aiud Citadel is a well-preserved 13th-century defensive fortification located in the center of Transylvania. Originally constructed as a refuge for the local population against Tartar invasions, it evolved into a complex featuring multiple distinct towers built by various craft guilds. The perimeter wall encloses a central courtyard that houses the Reformed Church, dating back to the late Gothic period. Several towers remain intact, including the Tailors', Bootmakers', and Coopers' towers, each representing the guild responsible for its defense. The site is one of the oldest and most intact urban fortresses in Romania, surviving numerous conflicts since the Middle Ages. Archaeological excavations have revealed layers of occupation predating the stone fortification. The fortress walls feature distinct Renaissance and Gothic architectural elements indicative of successive renovations. Today, the complex serves as a historical landmark and cultural venue.
