# Harlech street that has proved the world's steepest

![Harlech Castle](https://www.celticos.com/img/asset/YXNzZXRzL2ZlYXR1cmVkLWltYWdlcy8yMDE3MDkyMl8xMTEwMjMuanBn/20170922_111023.jpg?w=1440&fm=webp&q=55&s=67184d446138eadaa2ecf5ee410fddca) Harlech Castle  

For years the people living in a north Wales town have been convinced their street is the steepest in the world.

Now, after employing surveyors, liaising with the council and submitting their bid to Guinness World Records, the residents of Harlech, Gwynedd are celebrating that fact.

The gradient along the steepest part of Ffordd Pen Llech has been officially registered at a back-breaking 37.45%.

That makes it steeper than the previous record holder, Baldwin Street in Dunedin, New Zealand, which is a "gentle" 35% at its worst.

Not only now is Harlech famous for its historical castle which you can visit when touring.

This day is a mix of roads less travelled and a hidden but not a secret masterpiece. We begin by travelling through the south of the county of Gwynedd through quiet coastal villages and into Harlech where the fourth of the Iron Ring of Edwardian castles still rises majestically above the shore. Like the other three, the castle is well preserved. However, its quieter location means you are often able to let your imagination run wild and imagine yourself defending an outpost in dangerous territory.
