Holy Island, also known as Lindisfarne, is a tiny island off the coast of Northumberland, England. It's only 2 square miles big and is connected to the mainland by a causeway that disappears at high tide. This place has some serious history - it was a religious hotspot back in the day, with St. Aidan setting up shop there in 635 CE to convert the Northumbrians. The monks even produced the famous Lindisfarne Gospels. But things got dicey with Danish raids, and they had to bounce in 875, taking St. Cuthbert's body with them to Durham. The monastery was refounded later on and even garrisoned in the 16th century. Nowadays, it's a cute little tourist spot with a village and some essential services like coast guard and lifeboat stations. And hey, the population is a cozy 190 people.
