St Andrews Cathedral (Ruins) in Fife

You're standing at the ruins of St Andrews Cathedral, once the beating heart of the medieval Church in Scotland. Start with those two tall, slender gables still standing. They give you a sense of just how huge this place was. It was the largest church ever built in Scotland. Now glance down at the grass. The cathedral's ground plan has been cut into the turf, so you can trace where the walls and pillars once stood.
