In 1637, Scottish astronomer James Gregory drew a line across the floor of his St. Andrews laboratory and, without fanfare, established what could have become the world's reference point for time itself.
A meridian is simply an imaginary line running north to south—the kind astronomers use to measure longitude and divide the Earth into hemispheres. Gregory's version was precise, deliberate, and nearly 200 years ahead of Greenwich.
But history, as it often does, sided with power. When representatives from 22 countries gathered in Washington, DC in 1884 for the International Meridian Conference, they chose Greenwich. England's dominance in shipping and global trade tipped the scales. Gregory's line, positioned a few miles west, would have created a 12-minute time difference and placed London in the Western hemisphere instead of the Eastern. Had things gone differently, we'd all be syncing our watches to STAMT—St. Andrews Mean Time—instead of GMT.

The King James Library commissioned a brass meridian line set into the pavement outside Gregory's original laboratory on South Street, following the exact path of the wooden line he'd drawn on the laboratory floor nearly four centuries earlier.
It's a modest memorial—just a line on the ground—but it marks something worth remembering: that progress isn't always linear, and sometimes the most important breakthroughs belong to places the world forgot to notice.
Today, visitors can stand astride the line with one foot in each hemisphere, set their watches to 1637, and briefly exist in a timeline where Scotland kept better time than the rest of the world.
