The Water Works at Buffalo Bayou Park is one of the major attractions of the sprawling landscape. Popularly called 'Cistern', it served as Houston's first drinking-water reserve built underground. Constructed in the year 1927, it was abandoned when the authorities could not trace a leak source. Atop the historic site, Water Works commands some spectacular views of the city skyline. Bordered with some dense shrubs, it renders itself well for open-air events and performances.
