Baker Street Station in London. The top picture and bottom picture show the same platforms, 160 years apart. The platforms were once used by the Metropolitan Railway, but today, the Hammersmith & City and Circle Lines stop here, with the Metropolitan line being transferred to another set of platforms at the station.

The history of a city is often the history of its infrastructure.

The history of modern infrastructure starts with the Romans, with their many famous infrastructure projects, from roads to aqueducts, still impressing archeologists today.

The industrial revolution completely unlocked the potential of modern transportation, with modern technology like trains and cars enabling the rapid expansion of cities. This advancement led to the modern suburb, changing the way people live forever.

Still, there are obviously bad parts about this infrastructure growth. Roads, and to a lesser extent, railways, require a lot of land, and entire neighborhoods have been flattened to make way for freeways. However, this is more often than not a necessary evil.

We'll question you on your knowledge of how cities were built, expanded, and destroyed and how this relates to infrastructure. Get ready!
