Definition of impluvium in English:



  • The square basin in the centre of the atrium of an ancient Roman house, which received rainwater from an opening in the roof.

    • ‘The ancient Romans used the water collected in the impluvium to supplement their aqueduct system.’
    • ‘The eroded surfaces are now masked as damp woods which have invaded impluvia, gorges and escarpments.’
    • ‘A wellhead next to the impluvium provided access to the water stored in the cistern.’
    • ‘North of the impluvium you see an elaborate cantibulum resting between the two northern-most columns.’
    • ‘Further to the impluvium there was an underground tank connected to it which could catch any excess rainwater.’


Latin, from impluere ‘rain into’.
