While I don't actively plan my visits around the presence of Victorian cast-iron urinals, it's always a joy to come across them - at the National Railway Museum, York, the Jewellery Quarter in Birmingham, and most recently, St Fagans National History Museum, Wales.
The Welsh example is technically Scottish, since it was cast by the omnipresent Walter Macfarlane & Co at their Saracen Foundry. However, it spent nearly a century in Llanwrtyd Wells before moving to St Fagans in 1978.
Like all Macfarlane's work, the urinal is full of elegant and decorative detail. A particularly nice feature, though, is the admonition cast into a panel of each stall to 'please adjust your dress before leaving'.
