Viking Hogback Stones, Old Govan Church, Glasgow

Visited Old Govan Church a couple of weeks ago and took some pics with the permission of the very helpful and knowledgeable guides there. Govan is well-known as an industrial powerhouse which, over the past 150 years, has built an incredible number of the world's largest ships.
However the town, now part of the city of Glasgow, has a long and largely-forgotten history as one of the earliest seats of Christianity in Scotland and the main church of the Kingdom of Strathclyde, the lost kingdom of the northern Britons.
In AD 870, Vikings, who had been based in Dublin, destroyed Dumbarton at the mouth of the Clyde, which had been a major power centre in the centuries after the Romans departed from Britain. The stones below are considered to have been grave markers. More pictures from the Church, including the grave of St. Constantine, to follow.
