The former lockkeeper’s house at the 9th Lock on the Grand Canal in Dublin is for sale by Waterways Ireland (must be in need of some money for Thon Sheugh).
The fact that there is only an aerial photo of the site suggests that the interior is appalling and, in fact, the sales blurb declares the property to be “in need of a full renovation”. However, as the building is a protected structure, this will complicate any such renovation.
