This exists

As do people who will spontaneously invite you to go at noon on a Sunday, and a train that takes you to an elevator that takes you several stories to a citadel so far north up the Hudson that there are thickly treed banks on the Jersey side and sailboats in the water - though still tenement apartment buildings below you on the Manhattan side. The Cloisters is a branch of the Met, constructed out of chunks of mediaeval abbeys and churches from Western Europe. It's quiet and it smells good.
