Centuries Depending on the Sea

To Celebrate Wales Year of the Sea we’ve put together an article about Caernarfon amazing history by the sea -It’s no secret that Caernarfon defends the Menai Strait’s mouth from the exposed open water of the Irish Sea.

Caernarfon position on the mouth of the strait was in order to defend this integral strategic position, an important route to speedily access the North and West Coasts of Wales, as well as overseeing passage to Anglesey.

Supplies to Caernarfon Castle and it’s surrounding town would always come by sea due to the Welsh forces’ prowess in convoy ambush when transporting supplies over land, and so in using the seas they would not be able to use their guerrilla ambush techniques.

A School for Sailors

Another amazing fact about Caernarfon is that it was the location of a school for sailors and seamen. It was run by a woman by the name of Ellen Edwards who came to live in Caernarfon during the 1830s. She taught navigation and seamanship to hundreds of local men until her death in 1889. She was daughter of captain William Francis of Amlwch, Anglesey who himself had been a teacher of navigation. In her final years she was assisted by her daughter, Ellen Evans. I no-doubt don’t have to point out that opportunities for women have always been very limited, so to open a school of such success is an unprecedented achievement for a woman of that time. I’m sure she would have been to the Black Boy Inn a few times!

Home of the World’s Oldest Yacht Club

Today, Caernarfon is home to the Royal Welsh Yacht Club, based on Porth yr Aur which is the oldest yacht club premises in the world. It offers spectacular view of the Menai and of the old castle town.

The Logboat of Caernarfon

The Logboat was discovered in Caernarfon in the 20th century. It had spent time outside of garages in Caernarfon and defy before being acquired by the Llyn maritime museum in the 1970s. Research conducted into it confirmed that it is constructed from a tropical hardwood likely to be from West Africa. Ethnographic comparison reveals that it resembles those found in the Niger Delta, West Africa with its pointed bow and stern seat.

One of the possibilities is that the trading ships that sailed from Liverpool to West Africa trading palm oil, the local krooboys (young African man working in the ‘crew’) would paddle over the their logboats to find work on the vessels. Every now and then these kroo boys would stay on the vessel back to England. However rather than paying for unloading costs at ports, their log-boats were thrown overboard. The Caernarfon Logboat could be one of such examples, after being thrown overboard it could have floated into Caernarfon’s waters.

Porth yr Aur: Caernarfon’s Water Gate

The Royal Welsh Yacht Club’s clubhouse sits inside Porth yr Aur, the “Golden Gate” – one of two water gates built directly into Caernarfon’s town walls to give the castle and town access straight onto the Menai Strait. It’s a short, easy walk from the Black Boy Inn along the same medieval walls that once defended the town from land and sea alike.
