History

Cornhill is the group of buildings around the original Porthmadog harbour (Cornhill Wharf), which was built 1821-4. It became the commercial centre of the port and in 1833 Samuel Lewis noted that 'many good houses have been built, and a considerable trade is now carried on'. Buildings in Cornhill included houses, shops, bank, offices and workshops. In 1886 there were sail makers, 2 block and spar makers, 2 public houses, 4 grocers, butcher, ironmonger and a shipsmith. In addition, the Bwlch-y-Slate Quarry Co, Carnarvonshire & Merionethshire Steamship Co, Workmen's Benefit Building Society, Davies Brothers Slate Merchants, Parry & Co and Prichard Brothers ship brokers all had offices in Cornhill.

No 21 was built in the second quarter of the C19 and shown on the 1842 Tithe map, 1871 Tremadog estate plan and 1888 Ordnance Survey.
