Barred Culvert Portal with Timber Headwall

A large drainage culvert set into a shaped groundwork slab, with a heavy corrugated pipe running back from a timber-framed headwall. The face is boarded in weathered planks with a broad arched opening, and the arch is closed off by a riveted iron grille of vertical bars.

Wing walls and an angled buttress brace the headwall on one side, and a plank apron runs out from the sill onto the ground, with moss and grass tufts creeping up the stone at the edges.

A useful piece of layout infrastructure: run it under an embankment, a road crossing or a rail fill. The barred gate also makes it a natural sewer entrance or dungeon mouth on a skirmish board, or a hiding place in a horror scene.
