Two tall, well-matched portal stones mark the entrance at the north-east end of the structure, framing a gallery that stretches roughly 4.2 metres along a north-east to south-west axis. What makes it quietly puzzling is its ambiguous identity: court tombs and portal tombs are related but distinct Neolithic monument types, the former typically featuring a semicircular forecourt used for ritual activity before the burial chamber, the latter defined by its imposing entrance stones and simpler layout. This structure shares enough features with both that classifying it neatly is not straightforward.

The tomb was examined and documented by archaeologists Ruaidhrí de Valera and Seán Ó Nualláin in their 1972 survey of megalithic tombs across the Irish midlands and west. Their assessment was careful rather than definitive: they acknowledged the monument could represent a hybrid form, though they considered its affinities to lie closer to the court-tomb class on balance. The surviving fabric tells part of the story. The southern side of the gallery has largely disappeared, while the northern side has been absorbed into a field fence, the kind of practical reuse of ancient stone that was commonplace in rural Ireland for centuries. A large slab resting within the gallery area, leaning against the northern side, may once have formed part of the roof, displaced at some point in the monument's long history of slow dismemberment and casual alteration.
