Keeping Caernarfon's history alive is very important to Aaron Evans and fellow members of Gwydion Heritage. He's picked one exhibit at this year's exhibition at Celtica, Victoria Dock, which shows the grand ideas entrepreneurs had for the town in the 19th century.

"We have an eight foot long panoramic impression of the proposed development of Victoria Dock in 1860.

The Harbour Trust commissioned a redevelopment of the dock due to a lack of capacity at the quayside, and they came up with a very grand plan; far more ambitious than the dock we have today. The original idea would have been twice, if not three times the size of the current dock.

The chairman of the Harbour Trust was Sir Llewelyn Turner, a great philanthropist of the time. He was responsible for bringing clean water to Caernarfon, made repairs to the castle and helped launch the first lifeboat.

He saw the transformation of the dock as being a chance to create a great exporting port, to match Holyhead.

But the plan never came to total fruition because they hadn't anticipated the impact of the railways, when much of heavy industry began to use trains instead of ships.

But Victoria Dock remained significant in the exporting of slate and importing of timber from America. It was also important for immigration; the famous Hindu ship which advertised to take people from Caernarfon to North America set sail from this dock.

This is the second exhibition we've created. Gwydion Heritage was first set up by a group of amateur historians just before the Millennium, to celebrate the history of Caernarfon's people.

The only historic museum we have here is the castle; there's nothing about the town and its inhabitants. Every historic town in England has a heritage centre, but even though Caernarfon has a huge and rich history, we have nothing, and nowhere to keep our treasures.

Some very valuable gold coins were found in the Roman fort at Segontium, but were sent to Cardiff. Some armour from the Napoleonic period found here is now in Liverpool.

I'm a history teacher and feel it's vital to teach our children about their town's history, but I can't afford to take them to Cardiff to see artefacts from their own town.

They're doing so much regeneration work in Caernarfon at the moment, on the town and the old dock. So we're hoping there will be room for a heritage centre, too. This would be great for locals and tourists.

This display will be open until the autumn, but we're really hoping that this time, something permanent can be set up in the town." By Aaron Evans
