As seen in the app On Coogan’s Bluff, there are stone retaining walls in High Bridge Park app creator Paul Kittas believes were overlooked in maps by the Friends of the Croton Aqueduct. Kittas tells us, “In 1848, one hundred and sixty seven years ago, the Croton Aqueduct was built here and it looks the same as when the workers walked off the site.” He built the app to allow the curious how to “explore a remote section of Manhattan on your own.”
