Royal Observatory Greenwich — Star-Gazing Tsar

Designed by Sir Christopher Wren and built for £520 using recycled materials, Flamsteed House at the Royal Observatory Greenwich in London was Britain's first purpose-built scientific research facility. In early 1698, the six-foot-eight-inch Tsar Peter the First of Russia visited the Octagon Room to observe Venus with John Flamsteed. This encounter inspired Peter to establish the Moscow School of Mathematics and Navigation in 1701.

Why did Tsar Peter the First visit the Royal Observatory Greenwich in 1698?

Look up at the building before you... Flam-steed House. The first purpose-built scientific research facility in Britain, designed by none other than Sir Christopher Wren. And here's a detail most people walk right past. This building was made from recycled materials — the bricks came from spare stock at Til-bury Fort, while the wood, iron, and lead came from a demolished gatehouse at the Tower of London. And the money for its construction? It came from the sale of decayed gunpowder. The whole thing cost just five hundred and twenty pounds. Britain's window onto the cosmos... paid for with rotten explosives.

Now, look up at the tall windows on the first floor. That is the Octagon Room — Flam-steed's Camera Stellata, a room fitted out for making observations of the heavenly bodies. Its great height accommodated four-metre-long pendulums inside the Tompion clocks built into the walls, and tall windows on six of its eight sides gave astronomers a panoramic view of the sky.

And it was Right Here, in early sixteen ninety-eight, that a very unusual visitor climbed those stairs. Tsar Peter the First of Russia arrived in England to learn about shipbuilding and navigation. His aim? To establish the first Russian Navy. He traveled incognito under the name Peter Mikhailov. At six feet eight inches, Peter was one of the tallest men in Europe — a fact very hard to disguise.

His entourage included four chamberlains, three interpreters, two clocksmiths, a cook, a priest, six trumpeters, seventy soldiers as tall as their monarch, four dwarves... and a monkey. Imagine That procession winding its way up Green-wich Hill!

Peter was interested in astronomy because of its links with navigation, so he visited the Royal Observatory, observing Vee-nus from the Octagon Room with the first Astronomer Royal, John Flam-steed. Picture it... The towering Tsar, peering through Flam-steed's telescope at that bright point of light, while England's finest star-mapper explained how the heavens could guide a ship across a featureless ocean.

Peter was the first tsar to leave Russia for more than one hundred years. And what he learned in This room, he carried home. Just three years later, in seventeen oh one, he founded the Moscow School of Mathematics and Navigation, situated in the SukhArev Tower, providing Russians with technical education for the first time — its curriculum devoted to producing sailors, engineers, cartographers, and bombardiers. That school traces its origins directly to Peter's vision — and eventually became the Saint Petersburg Naval Institute.

One evening of star-gazing in this octagonal room... and a whole nation learned to navigate by the sky. In Dept-ford's royal dockyards he acquired skills that helped him raise a Russian fleet. Here at the Royal Observatory, he studied to improve Russian navigational skills. The knowledge that flowed from these walls didn't just chart British seas. It launched an Entire navy... a thousand miles to the east.
