This was once a quay, marked on maps and remembered in the placename Beaverstown, yet the physical structure has been so thoroughly erased that only a slight depression in the land now hints at what stood here.

The quay formerly consisted of two roughly parallel banks, each running for approximately 60 metres, with a marshy hollow between them where the tide could come and go. That arrangement, a sheltered channel flanked by raised embankments, would have allowed small vessels to load or unload at low water while remaining somewhat protected from the estuary's currents. At some point, both banks were levelled, and the record compiled by archaeologist Geraldine Stout, uploaded to the national monuments database in August 2011, notes that all that survives is the elongated hollow that once lay between them. The Rogerstown estuary is a significant tidal inlet, and small quays like this one served the quiet commercial life of the north Dublin coastline for generations, handling goods, turf, and agricultural produce that would otherwise have required long overland journeys.

The site sits immediately east of Raheen Point and is most legible, to the extent it is legible at all, at low tide when the hollow retains water and its shape becomes clearer against the surrounding ground. The estuary itself is a protected bird habitat, so the area draws naturalists as well as those with an interest in landscape history. There is no dramatic structure to photograph, no interpretive panel to consult. What remains is a subtle landform, an impression in the ground that rewards the kind of attention you need to bring yourself, knowing in advance what you are looking at and what, almost entirely, is gone.
