Grand Slam occasions have generally meant glory days in Wales.
If Warren Gatland’s side are looking for an omen this weekend in their quest for a Six Nations triumph against Ireland on Saturday and win a 12th Grand Slam, they can reflect on recent history.
These rare days in the Welsh capital on the final day of the tournament have generally proved an overwhelming success over the years.
Most occasions have been magical moments of celebration with Wales triumphing in front of their home crowd and sparking wild scenes.
When Wales have needed to deliver on the final weekend with the Grand Slam at stake, they have tended to triumph.
There are always exceptions to the rule. In 1988 Wales had secured the Triple Crown but failed to win a tournament clean sweep on home soil when France defeated Bleddyn Bowen’s side 10-9.
That has been the glaring anomaly. BBC Sport Wales looks back at some of the memorable moments that have provided Grand Slam fever in Cardiff as Gatland attempts to become the first coach to win three tournament clean sweeps.
