This monument was unveiled for the 55th anniversary of the battle, in May 1999.
It's an 8.5-metre monument designed by the Polish sculptor Gustaw Zemla, honoring the 2nd Polish Corps. Resembling the outline of Italy with a number of eerie, battle-related elements built into it, the monument also features a pair of wings, supposedly representing Nike and the Polish Hussars.

The Battle of Monte Cassino was actually a series of four intense and sometimes controversial battles that took place between January 20 and May 18, 1944, culminating at a 1,300-year-old Benedictine monastery on the top of the 1,100 metre Monte Cassino in southern Italy. After the successful Allied landings in Italy in September 1943 a route was needed from the Allied position north of Naples to Rome, and the only way through was via the Liri Valley. Blocking the valley was a mass of German-occupied hills around the town of Cassino. Involving British, US, French, North African, New Zealand, Ghurkha and Polish troops, fierce battles raged against the Germans on a slow and brutal advance towards the monastery, whose eventual capture would give the Allied forces the access they needed to open the road to Rome. At a cost of over 25,000 lives including the deaths by heavy allied bombing on February 15 of a number of Italian civilians who were taking refuge in the monastery, the final battle ended on the morning of May 18 when a reconnaissance group of soldiers from the Polish 12th Podolian Uhlans Regiment finally reached what was by then an empty and completely devastated monastery. The Battle of Monte Cassino paved the way for the Allied advance on Rome, which fell on June 4, 1944, two days before the Normandy invasion, and is one of Poland’s proudest military achievements.

Red Poppies on Monte Cassino

D`you see those ruins on the hill-top?
There your foe hides like a rat!
You must, you must, you must
Grab his neck and cast him from the clouds!
And they went, heedless of danger
And they went, to kill and avenge
And they went stubborn as ever,
As always - for honour - to fight.

Refrain:

Red poppies on Monte Cassino
Instead of dew, drank Polish blood.
As the soldier crushed them in falling,
For the anger was more potent than death.
Years will pass and ages will roll,
But traces of bygone days will stay,
And the poppies on Monte Cassino
Will be redder having quaffed Polish blood.

They charged through fire like madmen,
Countless were hit and fell,
Like the cavalry at Samosierra,
Like the men at Rokitno years ago.
They attacked with fury and fire,
And they got there. They climbed to the top,
And their white and scarlet standard
They placed on the ruins `midst clouds.

Refrain:
Red poppies on Monte Cassino ....

D`you see this row of white crosses?
Polish soldiers did honour there wed.
The further you go, the higher,
The more of such crosses youl'l meet.
This soil was won for Poland,
Though Poland is far away,
For Freedom is measured in crosses
When history from justice does stray.

Refrain:
Red Poppies on Monte Cassino...
