Buffalo Bayou Park Cistern

A 1926 underground drinking-water reservoir with 221 columns, now an eerie art and sound installation space. Guided tours run every half hour. Unlike anything else in Texas.

Insider tip

Reservations are required, not merely recommended - and children must be 9 or older, so this is not a stop for a family with toddlers.
