More than 50 geoglyphs with various shapes and sizes, including a massive swastika, have been discovered across northern Kazakhstan in Central Asia, say archaeologists.
These sprawling structures, mostly earthen mounds, create the type of landscape art most famously seen in the Nazca region of Peru.
Discovered using Google Earth, the geoglyphs are designed in a variety of geometric shapes, including squares, rings, crosses and swastikas (the swastika is a design that was used in ancient times). Ranging from 90 to 400 meters (295 to 1,312 feet) in diameter, some of them are longer than a modern-day aircraft carrier. Researchers say that the geoglyphs are difficult to see on the ground, but can easily be seen from the sky.
