The castle that isn't
Morris Castle or Castle Graig (Castell Morris or Castell Craig) is a ruined residential building situated on the Cnap-llwyd common in the Trewyddfa area of Swansea. It was constructed by Sir John Morris to house the families of workers and is one of the earliest examples of a tenement building.
This website takes up the story:
In the late 18th century industry was booming in the area around Swansea in Wales. Ever more sophisticated machines were powering the various works, and coal was required to fuel the industry. With copper works and coal mines, John Morris was a wealthy man and lived in style at the newly-built Clasemont , a grand classical mansion. The unusual structure he had constructed to house some of his workers was also eye-catching, but within decades it was dismissed as a folly.
John Morris (1745-1819) was a partner in Lockwood, Morris & Co., the biggest of the copper smelting enterprises in the area, and the rapid expansion of the works meant further housing was needed for his workforce. On the hill called Cnap Lwyd he built a vast fortress-like structure, with four corner towers and a central courtyard, which quickly became known as Morris Castle. It provided homes for a number of families (accounts vary between 20 and 40), and was one of the earliest examples of a tenement for estate workers. Probably designed by architect John Johnson, who also designed Clasemont (or Clas Mont or Glasmount), the castle had decorative quoins and battlements made of copper slag, a by-product of the smelting process. The waste could be moulded into blocks, their darker tone and soft sheen contrasting nicely with the local building stone.

But whilst handsome, Morris Castle was not practical. A passer-by in 1776, only a few years after it was completed, found there was already dissent: ‘Mr Morris has built a very large house on a high hill which makes a striking appearance for the Workmen to dwell in, but they complain of clambering up to it’. By 1796 the grand hillside fort was shown to tourists as ‘Morris’s Folly’: the development had been an experiment that failed. Would the workpeople ‘go the summit of a high hill and live in “flats” … when there was plenty of space for pretty little white-washed cottages?’, queried a later writer, before concluding: ‘They would not!’.
Morris learned from his mistakes, and when he created a new town for his workers in the late 1770s, the buildings were conventional cottages and on lower ground. This planned settlement, named Morris Town or Morriston, thrived, and in 1819 the ‘houses for the poorer classes’, neatly arranged in straight lines, were considered ‘excellent and commodious’: by that date Morris Castle did not even merit a mention.
The ruins are very prominent and can be seen from large areas of Swansea. Given the name, it is not surprising that many people believe that they used to be some sort of fortification.
It is possible to walk up there, and I'm told the views are spectacular, but it isn't a feat I've attempted myself - yet!

Why not clean the area up and develop it as one of the 1st experiments in worker housing? A sort of early Titus Salt (mayor of Bradford) worker village. Others still exist.
