The Abbey was rebuilt after the war. In the early 1950s, President of the Italian Republic Luigi Einaudi gave considerable support to the rebuilding. Pope Paul VI consecrated the rebuilt Basilica on 24 October 1964.

The attention of the Allied Forces had switched to the battle in north-western Europe. 55,000 allied soldiers lost their lives in the Battle of Monte Cassino. On the German side, the losses were much smaller: 20,000 soldiers died.
