the oldest known wall paintings were discovered in a cave in
Cave painting The earliest known cave paintings/drawings of animals are at least 35,000 years old and were found in caves in the district of Maros, located in Bantimurung district, South Sulawesi, Indonesia, according to datings announced in 2014. Previously it was believed that the earliest paintings were in Europe.[1] The earliest figurative paintings in Europe date back to the Aurignacian period, approximately 30,000 to 32,000 years ago, and are found in the Chauvet Cave in France, and in the Coliboaia Cave in Romania.[2] The earliest non-figurative rock art dates back to approximately 40,000 years ago, the date given both to a disk in the El Castillo cave and a hand stencil in Timpuseng cave Sulawesi, Indonesia. There are similar later paintings in Africa, Australia and South America, continuing until recent times in some places, though there is a worldwide tendency for open air rock art to succeed paintings deep in caves.
Egyptian pyramids The earliest known Egyptian pyramids are found at Saqqara, northwest of Memphis. The earliest among these is the Pyramid of Djoser (constructed 2630 BCâ€“2611 BC) which was built during the third dynasty. This pyramid and its surrounding complex were designed by the architect Imhotep, and are generally considered to be the world's oldest monumental structures constructed of dressed masonry.[6]
