The historical heart of Lancaster, centred on Castle Hill, is particularly clear from this angle. The tallest tower is that of the Priory, with the Castle to its left. A little further to the left, the 'fingers' of the Millennium Bridge are visible, on the next loop of the River Lune. It mightn't be obvious that the river passes to the left of the blocks of flats at the left of this image. Even less obvious is that the point where the river disappears behind the trees is Skerton Weir, where the Lune becomes tidal.
