Queen Gisela played a fundamental role in spreading the Christian faith and Western culture in Hungary.

One of the twins died young, but the other, Edward Atheling, was brought up as a protégé of Queen Gisela, and regarded in that foreign court as the heir to the Anglo-Saxon throne.

In 1046 Gisela, her attendants, and a number of many Bavarian settlers left Hungary to return to Bavaria, where she joined Niedernburg convent in Passau and became the abbess.

Both are now safely protected in glass and gold cases, and are displayed in the basilica in the western Hungarian town of Veszprém, where Gisela once lived.

Blessed Gisela is depicted on a white limestone panel by Hungarian artist Sandor Kiss on the wall of the Chapel of Our Lady – Queen of Hungary in St. Peter's Basilica, Rome.
