The street has repeatedly yielded human remains during routine groundworks, and the burials keep accumulating without any clear explanation of who these people were, when they lived, or why they came to rest where they did.

The first discovery came in October 1951, when workmen laying sewerage pipes uncovered three skulls along with bones representing numerous individuals. At the lowest burial level, fragments of charred oak were found among the remains, a detail that is suggestive but ultimately inconclusive, since no associated objects were recovered that might help date the deposit. The absence of grave goods or datable material leaves the chronology open. More than half a century later, the street gave up its dead again. In 2000, archaeological testing ahead of building works near the courthouse car park encountered two further burials, though construction proceeded without fuller investigation. Then in 2003, monitoring of a pipe-trench along Castle Street, between ten and forty-five metres from its junction with Market Street, revealed additional burials at a depth of around 1.25 metres. That 2003 work was subsequently described in published excavation reports under the heading of urban medieval, suggesting the site fits into Trim's long history as a significant Anglo-Norman town, though the burials themselves remain undated.

What makes this place quietly unsettling is not any single dramatic find but the cumulative picture: an ordinary town street, dug up repeatedly over decades for pipes and foundations, each time returning human remains from an unknown population. Trim's streetscape continues to sit, largely unknowing, above them.
