I have passed this UNESCO biosphere reserve before on my way to Howth and decided leaving it for a separate trip later-on. It turned out today being a popular gem within Dublin Bay.

The history of this man-made island dates back 200+ years ago (only!), when the ongoing silting problem of the Dublin harbour and its River Liffey needed attention. After finally both Bull Walls (South and North) had been built, the channel into Dublin got deeper and the island bigger and bigger, by shifting currents! Smart.

Fair winds…

End of South & North Bull Walls.
