Largo di Torre Argentina is a large open space in Rome, Italy, with four Roman Republican temples and the remains of Pompey's Theatre. It is in the ancient Campus Martius.
The name of the square comes from the Torre Argentina, which takes its name from the city of Strasbourg whose Latin name was Argentoratum. In 1503, the Papal Master of Ceremonies Johannes Burckardt, who came from Strasbourg and was known as "Argentinus", built in via del Sudario a palace, called Casa del Burcardo, to which the tower is annexed.
Julius Caesar was assassinated in the Curia of Pompey, and the spot where he is believed to have been assassinated is in the square.
