In this episode, we scale the vertical heights of Edinburgh’s Old Town to understand how a 350-million-year-old volcanic plug created a "Manhattan of the Middle Ages." We analyze the Crag and Tail formation—a geological fluke that forced the city to build some of the world’s first high-rise tenements—and explore the architectural science required to keep 14 stories of rubble masonry standing on a steep slope.
