This rectangular structure, measuring roughly 9 metres north to south and 8 metres east to west, was built as a gateway with a passage running through its centre, though curiously it lacks the typical defensive features like portcullis grooves or gate rebates that you’d expect from such a building. The Civil Survey of 1654-6 records that Mary Newgent owned 199 acres here in 1640, complete with a castle, two mills, a weir, an orchard and several small cabins; a prosperous holding that speaks to the site’s importance in the local economy.

The tower’s design reveals its dual nature as both passage and residence. A narrow doorway on the western wall opens onto a newel staircase that spirals up through three upper floors. The first floor sits beneath a barrel vault that spans the entrance passage, whilst the second and third floors each contained square chambers lit by simple rectangular windows. These upper rooms were supported by wooden joists set directly into the walls, though notably absent are any signs of fireplaces or garderobes, suggesting they may have been located in the now-destroyed western wall. The northern face of the tower features four broad machicolations at second floor level; stone brackets that once allowed defenders to drop objects on attackers below.

By the time Austin Cooper sketched the tower around 1785, it had already fallen into ruin, though his illustration shows the gateway passage still open and two upper storeys intact. Today, both ends of the passage have been closed off and fitted with lintelled doorways, a later modification that transformed the open gateway into a more secure structure. Recent archaeological testing about 250 metres west of the tower turned up no related material, leaving many questions about the tower’s broader context and the extent of its associated buildings still unanswered.
