Mountain
The Serra de São Mamede is a significant mountain relief in eastern Portugal, rising within the Portalegre district as the highest point south of the Tagus River. Reaching a maximum altitude of 1025 meters, it forms an ecological island amidst the rolling plains of the Alentejo. Geologically, the range is distinguished by steep quartzite ridges oriented northwest-southeast, creating striking silhouettes. Because of its height, the Serra intercept more rainfall than the surrounding lowlands, resulting in a cooler, more humid microclimate that supports lush forests of chestnut and oak. Historically, the area is dense with archaeological heritage, featuring the Roman city of Ammaia and the fortified medieval village of Marvão. The Natural Park, established in 1989, preserves this diversity. The territory is also a vital sanctuary for raptors such as the griffon vulture and Bonelli's eagle, which nest in its inaccessible rocky cliffs.
