Fiskerton has received international archaeological attention on a number of occasions over the last two centuries following discoveries of Iron Age artefacts unearthed from the fenland peat around the village.

It appeared to have been repaired and added to every eighteen years or so in that period and the construction and maintenance of a walkway on such a scale at that time would have been a major feat of engineering.

[3] Twenty years later in further excavations more sections of the causeway were dug out, some of them containing posts several metres long, plus a complete spear, a currency bar, a sword, a dagger and some bronze fittings, all of which appeared to have been deliberately damaged before their burial.

The area around the site of the causeway, which is beside the road to the hamlet of Short Ferry, 1.6 miles (2.5 km) to the east, opened as a nature reserve and is currently managed by the Lincolnshire Wildlife Trust.

The sighting was reported by four girls: Rachel Rowan, 12, Nicki Handley, 11, Nicola Proctor, 9, and Joanna Brogan, 10, staying at a caravan park next to the Tyrwhitt Arms pub at Short Ferry, the hamlet in the eastern part of Fiskerton parish.[when?]

The girls, who fled immediately to seek help in the pub, also reported finding large paw prints at the location when they returned later.
