Temple of Trajan (also known as the Trajaneum) at the ancient city of Pergamon, located in modern-day Turkey.
The temple was built during the reign of the Roman Emperor Trajan, starting around 114 AD.
It was situated at the highest point of the Pergamon Acropolis and was dedicated to both Emperor Trajan and the city's patron goddess, Athena.
The structure's foundations were made of local andesite stone, which was then covered with white marble panels.
The columns visible in the image are in the Corinthian order, characterized by their ornate, acanthus-leaf capitals.
