Conimbriga is the largest excavated Roman settlement in Portugal, located near Condeixa-a-Nova, about 16 km south-west of Coimbra in central Portugal. The site was occupied before the Romans, but the city took its monumental form after Augustus's reign, when the Roman province of Lusitania was organised and a road linking Olisipo (Lisbon) and Bracara Augusta (Braga) passed nearby. In the 1st century AD the forum, baths and an aqueduct were built, and the city gained municipal status under Vespasian.

Portugal's most extensive and best-preserved Roman city ruins with remarkable intact mosaic floors depicting hunting scenes, mythological figures, and geometric patterns. The Roman baths, forum, and defensive walls are visible. On-site museum contains statues and artifacts.

Conimbriga is the largest excavated Roman settlement in Portugal, located near Condeixa-a-Nova, about 16 km south-west of Coimbra in central Portugal. The site was occupied before the Romans, but the city took its monumental form after Augustus's reign, when the Roman province of Lusitania was organised and a road linking Olisipo (Lisbon) and Bracara Augusta (Braga) passed nearby. In the 1st century AD the forum, baths and an aqueduct were built, and the city gained municipal status under Vespasian. Its wealthy houses were decorated with some of the finest mosaics in the Iberian Peninsula. The House of the Fountains has a large peristyle garden with water basins and jets that still function in places, while the House of the Cantaber and the House of the Skeletons preserve mosaic floors showing hunting scenes, mythological figures and geometric patterns. In the late 3rd century, threatened by Germanic invasions, the inhabitants built a hurried defensive wall, cutting through earlier buildings, and the city was sacked by Suebi in 465 AD. Its population then moved to nearby Aeminium, now Coimbra. Excavations began in the 1930s and continued under Portuguese and French teams; the site is run as an archaeological park with walkways over the remains. Conservation of mosaics is ongoing, with some covered or protected from weather. The Monographic Museum of Conimbriga, opened in 1962 and extended since, displays sculpture, pottery, coins, jewellery, glass, and tools found on site, arranged by theme and showing daily life. The ruins, museum, a cafe and a path to the walls give a full picture of urban life in Roman Lusitania.
