The wreck of the Mary Rose has started to collapse onto itself after conservationists finally managed to dry out the Tudor warship, 35 years after it was lifted from the seabed.

For decades the timbers of the ship needed to be sprayed with water and wax constantly to prevent them rotting but in 2013 the frame was enclosed and dried and now rests in a climatically controlled box in Portsmouth.

However the drying process has brought a new problem. As the water was removed and replaced with a special polymer, the huge wooden beams have begun to shift, warping the original shape.

Conservators have been forced to shore up the timber frame with scaffolding to prevent further movements and are monitoring the shift with special cameras.
