The Millennium Stadium has begun stitching artificial turf fibres to its natural grass roots using giant 'sewing machines'.
The Cardiff venue is nearing completion of its installation of a new hybrid pitch, which is set to be ready for Wales' autumn rugby internationals next month.
Up to 21 million artificial fibres are being stitched in to the surface using large scale, sewing machine-type equipment.
The 74,500-seater stadium has received criticism from players and officials over its condition in recent times, but is now taking a new approach to addressing the quality of its turf.
Head groundsman at the Millennium Stadium Lee Evan said: "This is a tried-and-tested system that features all over the sporting world.
"To see the stadium up there with the some of the greatest venues is just fantastic for me and my team, for Welsh rugby and the Millennium Stadium."
