Looking north from off to one side of the wheel. You can easily see the structure of the wheel
and the boats in both the top and bottom canals, ready for the wheel to revolve and swap them over.

This view looks directly along the top (Union) canal. You can easily see the main basin on the
left and the glass-walled visitor centre on the right. This angle shows the repetition of the
semi-circular and circular patterns, not at all obvious from ground level.
