No walls remain, no foundations have been excavated, no local landmark preserves the memory. The site exists now only as a cartographic trace, the kind of detail that rewards those who spend time with historical maps rather than the streets themselves.

The map in question is John Rocque's survey of Dublin, produced in 1756. Rocque, a Huguenot cartographer who worked across Britain and Ireland, was unusually diligent about recording industrial and commercial features alongside the streets and buildings that most maps of the period prioritised. His Dublin survey is consequently a remarkable document for understanding what the city's edges looked like in the mid-eighteenth century, when glassmaking was an active and moderately significant trade. Glasshouses of this era were typically substantial structures, requiring large furnaces capable of sustaining the intense heat needed to melt and work glass, and they were often sited away from residential centres partly because of the fire risk and partly because of the fuel demands. That Rocque noted this one suggests it was a recognisable feature of the local landscape at the time, even if its precise history, its owners, its products, and the date it ceased operating, have not been recovered in the available record.

Because there are no visible surface remains, there is nothing at the site itself to observe or photograph. The value here is in the archival rather than the physical. Rocque's 1756 map is accessible through several digitised collections, including holdings at Dublin City Library and Archive, and overlaying his survey against a modern map of the city is a rewarding exercise in seeing how much has been built over, cleared away, or simply forgotten. For anyone interested in Dublin's industrial past, or in the practicalities of pre-modern manufacturing, tracing this kind of vanished feature through cartographic sources is a different kind of site visit, one conducted at a desk rather than on foot, but no less genuine for that.
