Those 14 remaining pencil towers mentioned up thread, are located in San Gimignano, Tuscany a UNESCO world heritage site, stood since the mid 14th century, definately worth a visit / climb if you don’t suffer with vertigo like my ex wife did. Ice cream in the town also excellent. What is remarkable about this town and I suspect like many others across Europe that were abandoned after the plague, is how well they have been preserved. Construction techniques that not only survive but continue to be maintained.
The vessel in New York is not a building, it is however a bronze public structure, my only question would be is this structure accessible to all. If not then I would have a problem with that. Next time I’m in New York I will visit the highline
