Ffordd Pen Llech in Harlech is now officially the steepest street in the world, according to the Guinness World Records.
The street’s gradient has been verified as 1:2.67 (37.45% stretch over fall) by an independent surveyor.
It has taken the title from Baldwin Street in New Zealand. The street in the city of Dunedin has a gradient of 35%.
To win the title, Ffordd Pen Llech had to demonstrate the following:
the steepest gradient
the street must be a public thoroughfare
it must be fully paved
contain buildings running alongside the thoroughfare
The competition between Harlech and the city of Dunedin has become a popular talking point. Welsh professor, Anne Goulding, who lives in Wellington, spotted that both 'Welsh' and 'Dunedin' have been trending on Twitter in New Zealand.
