1st March - Grid and H shape???

I finally found a grid shape yesterday and forgot to post, still puzzling over an H shape. Finding this week a more difficult challenge than I realised!!
Fri - G - This was an airvent in an old chateau in France

 This was a modern tower of the church in St Polin france on the same trip

and taken this photo of Xanthe today in a very large puddle off FB. She has spent weeks with me looking for puddles, today she found this with Mum!!

Now off to look for an H shape???????? OK found a sort of H shape - Scarborough Castle :)

and of course a place I have never been to in London, this was at Heathrow airport!!
