Tunnel under Canal

Tunnel under canal including flight of steps to E

The tunnel is oriented NE/SW and is 33.6m long in all. The original part is that under the canal at the downhill end. Here there is a high stone revetment wall that follows the bend in the canal and a round arched tunnel entrance with set-back red sandstone voussoirs. This part of the tunnel is stone-lined with a semi-circular arched roof. The second phase of the tunnel is similar and continues the same alignment but the third, upper, phase which is directly under the house turns to a more E/W alignment; it has straight sides and the flat roof is also the floor of the house. Culvert to the south-east side. At the uphill end the tunnel entrance is beneath the gable end of the house and under a cast-iron plate. On the downhill side the towpath and tunnel are linked by a steep flight of stone steps, one step of which is inscribed 'B & A C Co' (Brecon and Abergavenny Canal Company).
