The discovery of enigmatic stone spheres gave greater archaeological significance to the Diquis Valley of Costa Rica. The near-perfect spheres vary in size: the smallest can be held in one hand, while the massive El Silencio is over 2 meters in diameter and 15 tons in weight. Many theories about the origin and purpose of the spheres have been proposed, but definite answers remain elusive. These spheres are the inspiration for our studio course at the University of Pennsylvania, spring 2002.

The National Museum of Costa Rica is developing the Parque de Esferas, or Park of Spheres. The park is to attract visitors and raise international awareness of these ancient artifacts, while also providing for research and protection of spheres on site. With this idea as a starting point, we will propose interventions that connect and activate the places where spheres are found.

Our proposal will also address The Landmarks Foundation's interest in repatriation of spheres. Hundreds of stone spheres have been removed from the Diquis Valley over the last thirty years, and Costa Rica's cultural heritage has been diminished. The Landmarks Foundation is working for the return of spheres currently scattered across the world. When possible, spheres should be returned to their original configurations. However, we will also design flexible and dynamic spaces to incorporate other repatriated spheres.

As spheres return and the park evolves, the region will be revitalized. Park activities will strengthen the local economy and identity by generating new employment opportunities, and increasing cultural knowledge and appreciation. Ideally, local residents will participate with the museum to develop and manage the park. It is our hope that this collaborative enterprise will bring together local townships, artists, archaeologists, and other partners. We will explore innovative sponsorship and promotional techniques to help ensure economic viability of the park. Ultimately, we will propose innovative programs that address archaeological, economic, and ecological issues, and that enhance the inherent qualities of the landscape.
