This is the view along historic Grope Lane, in the heart of medieval Shrewsbury.

The 'polite' version of how it got its name is that people had to grope their way along it in the dark to get from one end to the other.

However, the real reason is down to the fact that it was once a very busy red light district.

If you are wondering why Grope Lane is so narrow, it's because in those days buildings were taxed according to how much ground they occupied, rather than how tall they were.

This meant that when people ran out of space they added on upper storeys that were wider than the floors below and jutted out at the front.

In this way, they gained as much extra space as possible without increasing their taxes.

It also meant that over time streets became narrower as the buildings gradually moved closer to each other.

Incidentally, part of Grope Lane is built on the site of what was known as a plague pit.

Shrewsbury had three plague pits in total, and these were mass graves for victims of the Black Death, which wiped out half the population of England in the 14th century.
