The Pala d'Oro ordered from Constantinople had been installed on the high altar of St. Mark's in 1105.

In 1106 the church, and especially its mosaics, are damaged by a serious fire in that part of the city; it is not entirely clear whether any surviving mosaics in the interior predate this, though there is some eleventh century work surviving in the main porch.

The main features of the present structure are all in place by this time, except for the narthex or porch, and the facade.
