The Ordnance Survey map of around 1840 shows a dry dock at Mullingar:
So does the map of around 1900:
The photo below was taken into the sun, alas. The entrance to the dry dock is towards the top of the entrance. So why are there curved stones closer to the camera? Was there once a second dry dock? Or was a second dock planned without ever beinf constructed? Or was the dock moved from one site to the other?
The Ruth Delany and Peter Clarke histories say nothing about this. If you can shed light on the matter, please leave a Comment below.
