What makes this one quietly strange is that nobody can say precisely where it stood. In the townland of Lispopple, in north County Dublin, there was once a windmill, and beyond that single fact the ground becomes uncertain.

The record comes from Robert Simington's 1945 survey, which notes a mill in use in Lispopple, a small townland in the parish of Ballyboghill. Simington was a meticulous Irish Land Commission archivist who worked through the Civil Survey and Books of Survey and Distribution to map land ownership and land use across Ireland, and his reference establishes that milling activity existed here in some form. Ballyboghill itself is a modest rural parish in the Fingal area, and the broader landscape would have supported grain farming that made windmills a practical necessity across this part of Leinster in earlier centuries. Whether the structure was a tower mill, the more durable stone type that occasionally survives as a stump, or a simpler timber post mill, which leaves almost no trace at all, is not known. The site has not been precisely located.

For anyone drawn to the gap between a documentary record and the physical world it describes, Lispopple offers an unusual kind of visit. The townland lies within reach of Ballyboghill village, and the surrounding fields are flat and open, the sort of terrain where a windmill would once have caught a useful breeze. There is nothing to see in any confirmed sense, but walking the area with the Simington reference in mind gives a different texture to an otherwise unremarkable stretch of north Dublin farmland. The absence itself is the point, a place recorded but not found, preserved in a footnote and little else.
