Looking along the Lightmeridian

The Lightmeridian, 3°7’45” E is one straight line dedicated to light and art across Europe with a lighthouse at its beginning and end. All places (cities and towns) located on that meridian have the same hour, minute and second and are thus connected to each other on the same time. It becomes visible for a few minutes during the actual local solar noon, where the sun's rays fall completely vertically thanks to a correct cut in the architecture. See for yourself at Muze'um L, near Roeselare.
