This report concerns the design of a visitor center at the ancient monument of Cromeleque dos Almendres, situated in the Alentejo province of Portugal, well known for its ‘landscape’ of cork oak forests and prehistoric, monolithic monuments. The visitor center addresses the topic of creating a humble architecture that conveys and explains the unique astrological phenomenon that have shrouded the monument in mystery and religious worship through several millennia. The design aims to inform, intrigue and pace the visitors to explore the many functions of the center, reachable by foot. The humble expression of the facade culminates in an expressive interior, providing a multitude of functions, including an auditorium, a gallery and a wine bar.

The simplicity of the exterior expression of the visitor center improves the surroundings by contrasting it. The smooth transition from the terrain onto the fifth facade of the building provides the visitors a panoramic view of the valley. Below the visitors are invited into the darker subterranean exhibition to explore the multifaceted nature of the monument.
