The episode ends with a long, slow pan down the Caledonian Road today. A Sainsbury's lorry rumbles past a Greek bakery. A Somali café sits next to a gastropub. An old man remembers the smell of cattle. A young couple argues about parking permits.

The secret history? That a street designed for the rich became a refuge for the poor, a battleground for markets and supermarkets, and is now slowly being reclaimed by the very class it was originally built for. It's not just about architecture—it's about how London's housing policies, railway expansion, deindustrialization, and gentrification are written in the bricks and pavement of one single road.

The most dramatic turn comes in the 1980s. The historic Caledonian Cattle Market, which had defined the street’s character for over a century, was closed and sold off. In its place? The massive Sainsbury's superstore and a retail park. The episode captures the anger of older residents who saw the market as their identity. One pensioner recalls, "They took our market and gave us a supermarket. That's not progress—that's theft."
