The entrance to Portreath, CornwallWilliam Daniell, 1814

Despite it's small size Ayton says of Portreath; 'It is, nevertheless, a place of considerable bustle and business, and has a harbour, which is always crowded with vessels, that bring coals to it from Swansea and Neath, and return with copper and tin ore'

'While we were standing on the pier-head we saw a small brig running for the harbour, and though the weather was moderate, we could not see her, even willfully, advance towards the rocks, without a sense of anxiety and breathlessness'.
