Pont Cysyllte is a 17th-century road bridge crossing the River Dee near the village of Trevor, Wrexham County Borough, Wales. It lies 200 m west of Thomas Telford's Pontcysyllte Aqueduct.
The sandstone bridge is dated '1697', though it was substantially rebuilt during the 18th century, and only the south arch and part of the south pier are original. The bridge comprises three arches, with full-height triangular cutwaters between each arch, each topped by a pedestrian refuge. The older south arch has a span of 10.7 m and the north arches have spans of 14 metres and 14.2 metres.
The bridge has been regularly damaged by motor vehicles being, at its narrowest, only 1.83 metres feet wide. Vehicles are supposed to stop before crossing and give priority to any oncoming vehicle already on the bridge.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
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.
