Montgomery Castle Reservoir

Montgomery Castle Reservoir is a castle, fort or tower in Powys, Wales. Perhaps water filled the castle hole after the stones fell, making a mirror for the sky instead of a wall for men. Maybe the reservoir is the last room of Montgomery, the one no army could take because it has no doors to break. Imagine standing at its edge at dusk, not looking for a castle but watching the water hold the shape of every castle forgotten above it.
