Claim:
A glass roof for a motor vehicle, comprising: a laminated glass pane made of two individual glass panes, the two individual glass panes being joined with a glass joining material between the two individual glass panes and layered one with another such that the two individual glass panes contact each other along substantially an entire length of the laminated glass pane, the laminated glass pane being bent in a longitudinal direction and in a transverse direction, thus forming a three-dimensional bend, the laminated glass pane forming substantially an entire roof area between a front and a rear vehicle roof cross members, rigidly connectable to the vehicle body, and the laminated glass pane having a ventilation opening in the laminated glass pane, the ventilation opening being surrounded on all sides by the laminated glass pane; and an openable glass pane configured to fit in the ventilation opening in the laminated glass pane, thus tightly sealing a cutout in the laminated glass pane, each of the two individual glass panes having compressive stresses in their edge areas of at least 8 MPa, and wherein corners of the ventilation opening are rounded with a radius of at least 80 mm.
