Dragonmont is a volcano on the island of Dragonstone in the crownlands. The activity of the volcano gave rise to the island. The castle of Dragonstone is a small fortress located on the face of the volcano.
The volcano is still active, with pale grey steam rising from its hot vents. Beneath Dragonmont are rich deposits of dragonglass. There is much obsidian seen in the old tunnels beneath the mountain, found in chunks and boulders. Smallfolk live in villages below the Dragonmont, tillers of the land and fishers of the sea.
