Sundial Multicaja-Zaragoza, Horizontal sundial in Parque de Oriente, Zaragoza, Spain.

The Multicaja-Zaragoza sundial is a horizontal sundial in the Parque de Oriente, made of a 46-metre Corten steel gnomon rising 30.343 metres and an arc-shaped dial set into the pavement. The gnomon casts a shadow that can exceed 500 metres, and the dial's 3,000 marks let it indicate the zodiac sign and equinoxes and solstices.

The main structure was constructed in late October and early November 2009 through an agreement between Zaragoza's city government and Multicaja. This project emerged from collaboration between municipal authorities and a private entity to create a public landmark.

The design connects scientific precision with artistic expression, showing the creative approach to timekeeping that visitors see while walking through the park. Human silhouettes on the shadow-casting structure remind people of the personal connection to measuring time.

Visiting at different times of day helps you understand how the shadow moves and marks the hours as sunlight changes. The open park setting provides clear views of the structure and its shadow pattern from multiple angles.

The gnomon's tip can cast a shadow over 500 metres long, and on some days that tip moves at 7 metres per minute, fast enough to watch it travel. The dial in the Plaza del Reloj carries roughly 3,000 marks, letting the clock read the zodiac sign and the equinoxes and solstices.
