A random one-time reader landed on Twelve Mile Circle recently. That unknown visitor sought information about the Prime Meridian, and I’ll get to the specific request in a moment. I know I’ve discussed this meridian before. However, in searching my archives and after examining the Complete Index<\/a> I discovered that I’d never actually marked<\/em> the place where it all started in Greenwich, England (map<\/a>).<\/p>\n\n\n\n

More than nine years of writing 12MC and no photo? Really? Well, let’s fix that right now.<\/p>\n\n\n\n

I won’t spend a lot of time talking about it because I think most of us already know the story. Greenwich appeared in a number of 12MC articles, for example from an American perspective<\/a>. The agreed-upon line went through the Royal Observatory for a number of historical reasons. I’ll borrow some text directly from its website<\/a>.<\/p>\n\n\n\n

“In 1884 the Prime Meridian was defined by the position of the large ‘Transit Circle’ telescope in the Observatory\u2019s Meridian Observatory. The transit circle was built by Sir George Biddell Airy, the 7th Astronomer Royal, in 1850. The cross-hairs in the eyepiece of the Transit Circle precisely defined Longitude 0\u00b0 for the world. As the Earth\u2019s crust is moving very slightly all the time the exact position of the Prime Meridian is now moving very slightly too, but the original reference for the prime meridian of the world remains the Airy Transit Circle in the Royal Observatory, even if the exact location of the line may move to either side of Airy\u2019s meridian.”<\/p>\n<\/blockquote>\n\n\n\n

Modern calculations placed the meridian about 100 metres east of the line where all the tourists commonly gather. The Daily Telegraph noted<\/a> that a rubbish bin marked the actual line, not the fancy marker.<\/p>\n\n\n\n

A wonderful arch crossed motorway Autopista del Nordeste (AP-2) at kilometre 82 outside of Candasnos, Spain (map<\/a>). This was the object my random visitor hoped to find on the 12MC website. It very much marked the Prime Meridian and the search engine link landed on my Prime Meridian Through Spain<\/a>. However I didn’t include anything about the arch on 12MC because I didn’t know it existed. Whoever it was left disappointed, probably never to return.<\/p>\n\n\n\n

That troubling outcome, of course, led me to search for the arch and I found it without too much trouble. Unfortunately I never uncovered any information about its construction, who commissioned it, when it happened, or any other details. Precious little information even existed about the town of Candasnos itself. I consulted the Spanish version of Wikipedia to see what I could learn. It told me<\/a> that the economy depended on agriculture and people exiting the Autopista for services as they drove along through the countryside.<\/p>\n\n\n\n

[UPDATE<\/strong>: a kind reader sent me a link the Arco de Cristal<\/a> which provides the desired information. It was built in 1998 to liven up a particularly monotonous stretch of highway. Thank you reader!<\/em>]<\/p>\n\n\n\n

That little exercise turned out to be a bit of a bust. I came across an interesting website however, devoted entirely<\/a> to Prime Meridian markers. I could appreciate something like that, and I did, a kindred spirit who enjoyed a very specific geographic peculiarity. Why not use that as a source for finding a couple more fascinating Prime Meridian markers? That sounded like a great idea. I think I’ll do it.<\/p>\n\n\n\n

The meridian went through France so that seemed like a good place to hunt for more markers. I found a particularly nice one in the village of Neuvillalais (map<\/a>) in the Pays de la Loire region. According to French Wikipedia<\/a>, the name traced back to Latin, nova villa, meaning new town. Its residents didn’t have a demonym until 2016 when the municipal council declared they were all “les Neuvillalois.” That shouldn’t have fascinated me, yet somehow it did.<\/p>\n\n\n\n

They named the primary road through town Rue du M\u00e9ridien. Only one business existed within the village boundaries, a bar-restaurant-grocery store called Le M\u00e9ridien. A line made of cobblestones marked the Prime Meridian as it traversed a roadway intersection near the center of town. A giant globe marked its passage where it crossed the front yard of a church. More recent photos suggested that the globe might have disappeared sometime in the last couple of years. What a pity.<\/p>\n\n\n\n
