Motif

With a snip from Bing's picture of the day being included left.

Included because of the three very un-English spires, two left and one right. The ones which come to a line at the top rather than a point. The ones with only two axes of symmetry rather than the three or more, more usual with us.

I think you get stumpy versions on the top of posh French houses, perhaps on what they used to call hôtels particuliers, but nothing nearer home.
