The school is here shown from the east; it is viewed from across the river Thames. The general position of the chapel appears as it would be seen from this direction, but many of the other details of the buildings are invented.
The painting is dated on grounds of style. Canaletto was staying nearby at Windsor in 1747, but this seems to be a later work (http://www.nationalgallery.org.uk/paintings/canaletto-eton-college).
