Cyfarthfa Castle Lake

Cyfarthfa Castle Lake is a castle, fort or tower in Merthyr Tydfil, Wales. Perhaps the lake formed when castle works flooded a hollow, dragging stones and tools into green darkness. Maybe the water still holds the shape of what was built above it. Imagine rowing across at midnight and seeing a tower rise through the surface, rooms lit, stairs turning, waiting for the person who drowned the first time.
