It used to be a path through the woods and still is, but a wide open space now stands between you and the how. There are tunnels deep underneath the ground with pillars as support, walk across the grassy plain and you will come to a place where you walk under a arch and down a small walkway into the how. Inside is the armory, and walls with stories upon them and a room filled with carvings with the stone table in the middle. This is where the kings and queens of old stood with Caspian, to defeat his uncle and protect Narnia it has been rebuilt.
