Fish from the Thames?

This is another photo from my visit to Hampton Court Palace yesterday. 

The inner courtyard has several lit up  ‘fish’ which are impressive. This section is to relate to the fact that the Palace is alongside the river Thames and that for the first few centuries the main way to get to the Palace from central London was via the Thames. Also see the extra which was a moving display to indicate being under the water and was very effective as you walked through the ‘cloisters’ to go through to the gardens.
