A glasshouse structure for crops is described. With a view to assuring short air change times within the internal environment and the possibility of ventilating the glasshouse even in case of rain, the structure comprises a roof (1) with four pitches arranged to form a profile in the manner of a seagull's wings and comprises aeration apertures (5) on the external pitches of the roof with respective closure elements constituted by drop-leaves (6) capable of moving towards the interior. |
