In the 1940’s the first cattle grid in England and Wales was installed on the B4391 over the Berwyn from Llangynog to Bala, to deter sheep from wandering.
At that time cattle grids were not permitted on the public highways, but the land owner was influential in political circles.
Eventually legislation was passed in 1950 which permitted the placing of cattle grids on the public highway
The first official 'Cattle Grid' sign in the country was placed here on the 27 June 1952
