Did Mark Twain visit the Wenallt?

Dear Editors,

I was wondering as to whether you were aware of the visit of Samuel Langhorne Clemens, ‘Mark Twain’, to Cardiff in the 1800s and his potential visit to the Wenallt, Rhiwbina?

I came to discover this from my girlfriend who lives in Missouri and made me aware of a location called Cardiff Hill in the City of Hannibal which was Twain’s boyhood home town, and is immortalised in ‘The Adventures of Tom Sawyer and Adventures of Huckleberry Finn’.

Twain himself named this location as the vista from which strongly resembled that of a visit to Cardiff in which he looked down our own city.

My basic research has not narrowed down the dates of the visit, or more importantly the rough location where he stood looking down over Cardiff (although I would assume it was the Wenallt, or the Garth). As one who was raised and grew up in Rhiwbina, and still walks the Wenallt, I am intrigued and tantalised by this connection between our city and that of Hannibal, Missouri.

Kind regards,
