Arch of Time is a monument to Houston’s leadership in culture and energy.

It is a new permanent public artwork for Mason Park in Houston. Incorporating more than 60,000 functioning solar photovoltaic cells into the south-facing exterior of the sculpture, it will generously give 400,000 kilowatt-hours of clean electricity annually to power the park — equivalent to the demand of Mason Park. It will also provide 25,000 square feet of shaded, breeze-filled microclimate.

Functioning as a sundial, The Arch is also an interactive time-measuring device that creates a connection between the celestial and the terrestrial by means of a meticulously orchestrated casting of sunlight as a performance art onto the ground plane throughout each day. Each beam of light is uniquely composed through the seasons and hours of the day by the geometry of the artwork, which responds to the Earth’s rotation and the specific latitude and longitude of Houston.
