The Tour métallique de Fourvière (Metallic tower of Fourvière), a landmark of Lyon, is a steel framework tower which bears a striking resemblance to the Eiffel Tower, which predates it by three years. With a height of 85.9 metres and weight of 210 tons, the 'metallic tower' was built between 1892 and 1894.
During the Exposition universelle of 1914 in Lyon it had a restaurant and an elevator capable of taking 22 people up to the summit. Although used as an observation tower until November 1, 1953, nowadays it serves as a television tower and is not accessible to the public. At 372m, it is the highest point in Lyon.

The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
