Joe Ward, Grainne Walsh, Michaela Walsh and Aoife O'Rourke struck quadruple gold at the Nicolae Linca Golden Belt in Romania today.
Kellie Harrington, who was desperately unlucky not to make that five gold medals, and Kiril Afanasev, boxing for the fourth time in four days, lost out in the lightweight and heavyweight finals.
Today's haul, plus the bronze claimed in Galati, helped Ireland finish in top spot in the medals table.
Three-time European Elite champion Ward showed his class to score a unanimous decision over hot Romanian prospect Paul Aradoaie, while O’Rourke added to her growing reputation in the middleweight category versus Romania’s Onela Nane.
Michaela Walsh, the current EU champion, beat Romania's lively feather Lacramioara Perijoc and Ward's Sparticus BC team-mate, Grainne Walsh, saw off Perijoc’s compatriot Maria Borei in the welter decider.
Harrington, up against against Julia Tsyplakova, who Katie Taylor has beaten on a number of occasions in the amateur ranks, saw the controversial decision go to the Ukrainian lightweight.
There was also a big performance also from Afanasev versus Serhi Horskov in a bout which could have gone either way.
Zaur Antia and coaches John Conlan and Tom Murray were working Ireland's corner in Romania.
The Nicolae Linca Golden Belt is a memorial tournament to Romanian boxing legend Nicolae Linca who beat Ireland's Fred Tiedt in the 1956 welterweight final in Melbourne.
