I visited there a few years back, if you are in the area it is well worth your time. There is a large Polish cemetery there.
The Polish Cemetery at Monte Cassino holds the graves of over a thousand Poles and over two hundred Belarusians who died storming the bombed-out Benedictine abbey
For our freedom and yours
We soldiers of Poland
Gave
Our soul to God
Our life to the soil of Italy
Our hearts to Poland
