In the year 1106, it was for the second time injured by fire, but repaired before 1116, when it received another emperor, Henry V. (of Germany), and was again honored by imperial praise. Between 1173 and the close of the century, it seems to have been again repaired and much enlarged by the Doge Sebastian Ziani. Sansovino says that this Doge not only repaired it, but "enlarged it in every direction;" and, after this enlargement, the palace seems to have remained untouched for a hundred years, until, in the commencement of the fourteenth century, the works of the Gothic Palace were begun.

Venice was in the zenith of her strength, and the heroism of her citizens was displaying itself in every quarter of the world. The acquiescence in the secure establishment of the aristocratic power was an expression, by the people, of respect for the families which had been chiefly instrumental in raising the commonwealth to such a height of prosperity....

In the first year of the fourteenth century, the Gothic Ducal Palace of Venice was begun; and as the Byzantine Palace was, in its foundation, coeval with that of the state, so the Gothic Palace was, in its foundation, coeval with that of the aristocratic power. Considered as the principal representation of the Venetian school of architecture, the Ducal Palace is the Parthenon of Venice, and Gradenigo its Pericles.

Before it was finished, occasion had been discovered for farther improvements. The Senate found their new Council Chamber inconveniently small, and, about thirty years after its completion, began to consider where a larger and more magnificent one might be built. The government was now thoroughly established, and it was probably felt that there was some meanness in the retired position, as well as insufficiency in the size, of the Council Chamber on the Rio.

It appears from the entry still preserved in the Archivio, and quoted by Cadorin, that it was on the 28th of December, 1340, that the commissioners appointed to decide on this important matter gave in their report to the Grand Council, and that the decree passed thereupon for the commencement of a new Council Chamber on the Grand Canal.

The room then begun is the one now in existence, and its building involved the building of all that is best and most beautiful in the present Ducal Palace, the rich arcades of the lower stories being all prepared for sustaining this Sala del Gran Consiglio. In saying that it is the same now in existence, I do not mean that it has undergone no alterations; it has been refitted again and again, and some portions of its walls rebuilt; but in the place and form in which it first stood, it still stands; and by a glance at the position which its windows occupy, the spectator will see at once that whatever can be known respecting the design of the Sea Façade, must be gleaned out of the entries which refer to the building of this Great Council Chamber.

Cadorin quotes two of great importance, made during the progress of the work in 1342 and 1344; then one of 1349, resolving that the works at the Ducal Palace, which had been discontinued during the plague, should be resumed; and finally one in 1362, which speaks of the Great Council Chamber as having been neglected and suffered to fall into "great desolation," and resolves that it shall be forthwith completed.

The interruption had not been caused by the plague only, but by the conspiracy of Faliero, and the violent death of the master builder. The work was resumed in 1362, and completed within the next three years, at least so far as that Guariento was enabled to paint his Paradise on the walls, so that the building must, at any rate, have been roofed by this time. Its decorations and fittings, however, were long in completion; the paintings on the roof being only executed in 1400....

The works of addition or renovation had now been proceeding, at intervals, during a space of a hundred and twenty-three years. Three generations at least had been accustomed to witness the gradual advancement of the form of the Ducal Palace into more stately symmetry, and to contrast the works of sculpture and painting with which it was decorated—full of the life, knowledge, and hope of the fourteenth century—with the rude Byzantine chiselling of the palace of the Doge Ziani. The magnificent fabric just completed, of which the new Council Chamber was the nucleus, was now habitually known in Venice as the "Palazzo Nuovo;" and the old Byzantine edifice, now ruinous, and more manifest in its decay by its contrast with the goodly stones of the building which had been raised at its side, was of course known as the "Palazzo Vecchio." That fabric, however, still occupied the principal position in Venice. The new Council Chamber had been erected by the side of it toward the Sea; but there was not then the wide quay in front, the Riva dei Schiavoni, which now renders the Sea Façade as important as that to the Piazzetta. There was only a narrow walk between the pillars and the water; and the old palace of Ziani still faced the Piazzetta, and interrupted, by its decrepitude, the magnificence of the square where the nobles daily met.

Every increase of the beauty of the new palace rendered the discrepancy between it and the companion building more painful; and then began to arise in the minds of all men a vague idea of the necessity of destroying the old palace, and completing the front of the Piazzetta with the same splendor as the Sea Façade. But no such sweeping measure of renovation had been contemplated by the Senate when they first formed the plan of their new Council Chamber. First a single additional room, then a gateway, then a larger room; but all considered merely as necessary additions to the palace, not as involving the entire reconstruction of the ancient edifice. The exhaustion of the treasury, and the shadows upon the political horizon, rendered it more imprudent to incur the vast additional expense which such a project involved; and the Senate, fearful of itself, and desirous to guard against the weakness of its own enthusiasm, passed a decree, like the effort of a man fearful of some strong temptation to keep his thoughts averted from the point of danger. It was a decree, not merely that the old palace should not be rebuilt, but that no one should propose rebuilding it. The feeling of the desirableness of doing so was too strong to permit fair discussion, and the Senate knew that to bring forward such a motion was to carry it.
