The purpose of the present invention is to provide an agricultural greenhouse capable of efficient ventilation in both open and closed states of a curtain. In this agricultural greenhouse (1), the curtain (20) is configured to be able to change between a closed state in which the curtain reduces light that passes through a roof (100) and enters the inside of an outer shell (10), and an open state in which the curtain does not reduce light that passes through the roof (100) and enters the inside of the outer shell (10). A first intake fan (31a) is disposed above the curtain (20) in the closed state and a second intake fan (31b) is disposed below the curtain (20) in the closed state. A first exhaust fan (32a) is disposed above the curtain (20) in the closed state and a second exhaust fan (32b) is disposed below the curtain (20) in the closed state.
