Celtic Gods and Goddesses: top 10 explained

Tales from Celtic folklore and mythology still play a huge part across the Emerald Isle to this day.

Celtic folklore and mythology have played an important role in shaping many European customs and beliefs we are familiar with today – particularly in Ireland. One of the main aspects of Irish folklore involves ancient Celtic gods and goddesses.

Much of Irish mythology is made up of ancient Celtic gods and goddesses. These stories were passed down through oral traditions that began in pre-Christian Gaul, Iberia, Britain, and Ireland.

Many ancient Celtic folk tales that had their roots in Ireland have luckily been preserved in medieval Irish literature. So thankfully, we can read about their marvellous stories to this day.

If you want to find out more about Celtic mythology, here are the top ten ancient Celtic gods and goddesses.
