of Stuart. In 1509 Henry VII died at Richmond Palace. The fire of 1497 At Christmastide 1497 a great fire broke out in the king's private chambers, destroying a large portion of the palace. The Milanese ambassador, Raimondo Soncino, witnessed the blaze, and estimated the damage at 60,000 ducats, in modern money about $10 million or approximately £7 million. The fire lasted three hours and tore through the rest of the palace, causing panic and hundreds to flee. Hammerbeam roofs of the Middle Ages were a structural necessity as much as they were pretty architecture as they kept the heavy timbered roofs from caving in; they were the carpenter's equivalent of the stone vaulting found in Gothic cathedrals of the Middle Ages because as in famous examples, like Westminster Hall, they allowed the architect greater ability to achieve higher heights with thinner walls and evenly distributed the lateral weight. In as large a fire as described by Soncino the English oak beams of the great hall, a centrepiece of a royal Christmas, would have stood no chance of remaining upright and intact. They would have been engulfed in flames in the high temperatures well exceeding 270 °C. Much of the tapestry work of earlier ages was burnt to cinders, and losses included crown jewels and much of the royal wardrobe including a large amount of cloth of gold, at this time a luxury item only wearable by royalty and in the case of Sheen Palace it was a feature of the bedding. Accounts refer to Henry VII, his mother, Margaret Beaufort, and his wife, Queen Elizabeth, running for their lives, with the king barely making it out in time: one of the corridors nearly collapsed on top of him. As it was the time of the Christmas revels, also present during the disaster were all but one of the royal children, and all under the age of 10: Margaret, Mary, and a six-year-old Henry VIII, each of them described as being hurried out in the arms of their nursemaids. For Queen Elizabeth, this would have been a horrible blow: records show that as a child in the 1470s this was where she spent much of her childhood and otherwise this palace would have had strong associations with her mother Elizabeth Woodville: Edward IV left Sheen to his wife in his will. Soncino reports all of the events outlined above, and
