You're asking about the location of the Greenwich Meridian and which English town or city it passes through. Here’s a concise, clear answer. Answer
- The Prime Meridian, also known as the Greenwich Meridian, passes through the Royal Observatory in Greenwich, London. In practical terms, the zero degree longitude line runs through Greenwich, a district of London, United Kingdom. So the English town most strongly associated with the zero meridian is Greenwich in London.
Notes for context
- Historical and geographic context: The Greenwich meridian was established as the international zero meridian at an 1884 conference and is now defined relative to modern global standards; it serves as the starting point for measuring longitudes from 0° to 180° East and West.
- Greenwich remains a notable tourist and cultural landmark, with the Royal Observatory and the adjacent Greenwich Park, and is a UNESCO World Heritage Site in its historic area.
If you’d like, I can provide a quick map reference or a short walking route from central London to Greenwich to see the zero meridian marker.
