30th meridian east, meridian
The 30th meridian east is an imaginary line running from the North Pole to the South Pole across multiple continents. It crosses Arctic waters, Scandinavian forests, African savannas, lakes, and Antarctic ice sheets without passing directly through any major cities.
The 30th meridian began to be surveyed in 1879 by British astronomer David Gill to measure Earth's size and shape. This major survey arc, stretching roughly 7,100 kilometers from South Africa to Egypt across eleven countries, was completed in 1954 and contributed to precise Earth measurements.
The 30th meridian passes through regions where people rely on fishing in Scandinavia and herding in Africa for their livelihoods. Local communities along this line maintain traditions of music, dance, and storytelling that shape their daily rhythms and cultural identity.
The line is not visible on the ground as it is an imaginary geographic reference used by mapmakers and navigators. Those interested in following it can use maps and GPS to traverse diverse landscapes spanning from Arctic regions to Antarctic ice sheets.
Filmmaker Michael Palin traveled along this meridian from pole to pole and documented the diverse landscapes and cultures he encountered. This famous television journey brought the invisible line to life for audiences worldwide and revealed how different places are connected.
