14 Henrietta Street, Dublin, Ireland

Georgian townhouse to tenement buildings.  (Tenement = slum.)

extracts from its brochure:
"14 Henrietta Street is the story of 300 years of city life, all within the walls of this one address."
"Built as a townhouse for the elite of Dublin, 14 Henrietta Street had aristocratic beginnings: its first resident in 1748 was The Right Honourable Richard, Lord Viscount Molesworth and his wife Mary Jenney Usher...…."
"Built as a grand townhouse in the 1700s, 14 Henrietta Street was turned into tenements in the 1870s and removed so until the last families left in the latest 1970s."
"In 1911, the 19 buildings of Henrietta Street housed nearly a thousand people.  In number 14 alone, 17 families lived under this one roof."

The photo above was of some of the belongings in one of the better tenements.  The very bottom floor was perpetually damp and rat-infected.

The tour is guided, and it was delightful that some of the visitors had passed their childhood in tenements here and talked about their memories.
