Like something out the evil lair of a steampunk Bond villain, this amazing glass and iron dome has been quietly sitting underneath a lake in Surrey, England
for nearly 100 years. The stuff of urban legends, the massive dome was intended as a billiard room, though it has come to be known as "the ballroom under the lake."
The dome was part of a sprawling 9,000 acre palatial estate at Witley Park
built by the immensely rich J. Whitaker Wright
, whose downfall was almost as spectacular as his mansion.
And while impressive, the dome is just part of a larger underground complex that snakes around the lakes of Witley Park. Other notable sites include a boathouse, marble walled pools, serpentine hallways, several ornate entrances, and innumerable haunting skylights. The dome itself is topped with a statue, enigmatically placed in the middle of the lake.
