What type of monumental art have scientists discovered from the neolithic period, and where were they found?

Europe’s most remarkable Neolithic sites was uncovered by archaeologists near the border of Finland and Russia. The site included the remains of over 70 ancient settlements, but possibly the most intriguing discovery was a group of small rock carvings on the shores of Lake Onega. These simple drawings, or petroglyphs, depicted birds such as ducks, swans, and geese, as well as people engaging in warfare, performing religious rituals, and even skiing. The Karelian petroglyphs, as these carvings are known, are among the most complex and expressive examples of rock art in all of northern Europe.
