The Houston Cistern is considered a land monument. Here are some fun facts:
- 87,500 square feet or the size of 1.5 football fields
- 221– 25-foot tall, slender concrete columns span the space
- Holds 15 million gallons of water when functioning at capacity
- 8-inch thick concrete roof and tapered concrete walls range from 8 inches at the top to 18 inches at the bottom
- 17-second echo
- SWA Landscape Architect Kevin Shanley first called the reservoir “the Cistern” because it reminded him of the ancient Roman cisterns under Istanbul
