I grew up in this part of the world! Quite a strange juxtaposition seeing my home on the front page of this site.<p>So maybe I can offer some lesser known interesting context:<p>Wales is only some 300km west of London, yet I have childhood memories (some 35 years ago) of needing to try to speak Welsh to my elderly (in his 80s) neighbour who struggled with English.<p>There is a theory that English's use of "do" (so-called "Do-support") comes from the Welsh language. <a href="https://en.wikipedia.org/wiki/Do-support#Origins" rel="nofollow">https://en.wikipedia.org/wiki/Do-support#Origins</a><p>The stones for Stonehenge come from the Preseli mountains, a small range of blue-ish hills exactly on the coast where these lost islands are proposed.<p>There is a Welsh settlement in Argentina: <a href="https://en.wikipedia.org/wiki/Y_Wladfa" rel="nofollow">https://en.wikipedia.org/wiki/Y_Wladfa</a><p>Not strictly Welsh, but the Severn Estuary, which is the calm, funnel of sea between Wales and England, that invites ships into the harbour of Bristol, points exactly towards Newfoundland in North America. This Welsh-English estuary is where John Cabot made the second recorded voyage of a modern European to the New World[1]. Nowadays, we think of Airports as being the doorways to whole new worlds, but there was a time when it was the coastline and harbours of the South West British Isles that rang and echoed with the adventures, legends, captains, pirates, spices, gems and foreigners of unimaginable far away lands.<p>1. <a href="https://en.wikipedia.org/wiki/John_Cabot#Second_voyage" rel="nofollow">https://en.wikipedia.org/wiki/John_Cabot#Second_voyage</a>
