How did volcanoes shape Edinburgh?

Volcanoes played a significant role in shaping Edinburgh's landscape, particularly through the formation of the city’s iconic hills. The most notable is Arthur's Seat, an ancient volcano that erupted around 350 million years ago, creating a distinctive peak that dominates the skyline. Additionally, the remnants of other volcanic activity can be seen in the rugged topography and rock formations throughout the city, contributing to its unique geological heritage and scenic beauty. These volcanic features have also influenced Edinburgh's urban development and historical significance.
