The Thames wasn’t always the sluggish, muddy channel we know today. Back then, the river was wider and shallower, and the old London Bridge acted like a dam, slowing the flow to a crawl.
Add a few particularly brutal winters during the Little Ice Age—a period when Europe got so cold that the Baltic Sea froze over—and bam, you’ve got a six-foot-thick layer of ice. It wasn’t just cold; it was “your breath freezes into tiny icicles on your mustache while you complain about the price of roasted chestnuts” cold.
The first fair is a royal riot
The first recorded frost fair happened in 1608, but the most legendary one was in 1683-84. That winter was so severe that the ice lasted two months, and the river became a sprawling, rowdy carnival.
King Charles II wasn’t about to miss this. He showed up with his entire court, roasted an ox on the ice, and probably tried to buy a tin whistle from a vendor. At one point, a printer set up shop and sold “certificates of authenticity” proving you’d been on the frozen Thames—because nothing says I survived winter like a slightly smeared piece of parchment.
