Villers-sur-Mer is the first French town to be crossed by the Greenwich meridian! The Greenwich meridian passes through the Royal Observatory in Greenwich, United Kingdom. It then meets Europe in… Villers-sur-Mer!
The Greenwich meridian is the universal benchmark of space (for measuring longitude) and of time (for defining time zones). Situated opposite the 180th meridian, it divides the globe into Eastern and Western hemispheres.
