Portcurno Telegraph Museum
Was down there on holiday a few months back, and quite disappointed that this place was no longer open for a visit.
However must also give a mention to the Porthcurno Telegraph Museum also down near Lands End, which is a great visit for people interested in this kind of communications tech. It's a little more broad in topic (focussing more on the undersea cables mentioned in the article, some of which used to end at the museum building in its former life), but it gives a very good overview and is well worth a half-day visit.
Indeed I'm quite surprised it isn't mentioned in the article, given the overall topic and the other more off-topic attractions mentioned at the end.
