My photo-archive tells me that just over two years ago, in March of 2017, I photoed this photo, of Canonbury Tower:
Both ancient and modern, if you get my meaning. Probably built in the early 1500s, but to the casual eye it could be far more recent.
Photos by Pip Howeson, which include lots of the interior details, makes the antiquity of this tower block very clear. But you can photo many genuinely modern towers from Canonbury Tower. Here’s a slice of Howeson’s panoramic view from the top of it, of the centre of London:
You can only explore this building on two pre-arranged days each month, which is presumably why Howeson had to make do with weather that he might not have chosen. But a Big Thing spotter like me can still tick off all the names.
