The 4th-century Roman villa of Rabaçal is perhaps the most important ruin at the site of ancient Conimbriga, one of the largest Roman sites, and the best preserved, in Portugal. In the 15th and 16th centuries, it was repurposed as a cemetery and suffered from the removal of many architectural components for use in other local buildings being erected. In the 1980s the site was excavated, and archaeologists found important bas-reliefs as well as mosaics unique among other Roman sites throughout Portugal because of their high artistic quality and engaging motifs and figures, which suggest influences from the Near East. Two decades of excavation have provided invaluable information for scholars and the site has become a tourist destination because of the importance of the finds.
2004 World Monuments Watch
In 2004 the Villa was listed on the Watch due to concerns that the excavated areas were not adequately protected, putting the unique mosaics at risk of erosion from environmental factors as well as tourists. Subsequent to Watch listing, WMF received support from American Express to clean and stabilize the ruins and erect shelters to ensure improved protection of the mosaics. Maintenance and management plans were designed so that the site appearance and conservation conditions would be adequately maintained in the future.
The architecture, bas-reliefs, and mosaics in the villa of Rabaçal are unique and differ substantially in their figurative designs of the seasons, horse-drawn carriages, and a seated woman, than mosaics found in the rest of Portugal. Some geometric and plant patterns used bear no similarity to anything else known in the country. Studies have suggested that this décor blends the typical classical styles with vibrant North African traditions. The mosaics combine the colors, drama, and oriental luxuriousness of Byzantine art with the natural movement of the Greek ideal. As such, the mosaics, as well as the Roman Villa, represent the diversity of international exchanges within the ancient world.
