Conwy Castle, Wales, is one of the most prominent fortresses built by Edward I in the 13th century. It is one of the key castles of the king's "iron ring" of fortresses constructed in Wales. The stronghold was quite an expensive undertaking - it is estimated that Edward spent £15,000 (£162 million in 2009) on the construction, which makes it the most costly castle in the Welsh history. Today Conwy is declared a World Heritage Site.
The cliffs above the beach are a noted source of fossils from the Jurassic period. Fossil-hunters walk the beaches between Lyme Regis and Charmouth, but have to be wary of tides and landslips. The Dorset and East Devon Coast World Heritage Site covers 3 geological time periods; the Triassic, Jurassic and Cretaceous. These are showcased in the 3 rock types found along the coast.
The city and the archaeological site are located in what is now the San Juan Teotihuacán municipality in the State of México, approximately 40 kilometres (25 mi) northeast of Mexico City. The site covers a total surface area of 83 square kilometres (32 sq mi) and was designated a UNESCO World Heritage Site in 1987. It is the most visited archaeological site in Mexico.
