In 1071, just before his death, he commissioned builders to begin work on expanding and restoring St Mark's Basilica.

By his wish, he was buried at the church of San Nicolò al Lido when he died.

His tomb is above the main doorway, surmounted by a portrait bust which shows him wearing the "corno," the distinctive doge's hat.
