Conímbriga Ruins & National Museum
At Conímbriga's entrance is a portion of the original Roman road that connected Olissipo (as Lisbon was then known) and the northern town of Braga. If you look closely, you can still make out ridges worn into the stone by cart wheels. The road is just the beginning of the fascinating footprint left behind by the civilization that once dwelled here. A patchwork of mosaics reveals itself as you work your way across the paths. You'll be able to make out the foundations of several villas, including the House of Cantaber, named after a nobleman whose family was captured by invading barbarians in 465. The most extraordinary villa is the 3rd-century House of the Fountains, covered with mosaics depicting Perseus offering the head of Medusa to a monster from the deep. Private baths included a tepidarium (hot pool) and frigidarium (cold pool). Remnants of the central heating system that was beneath the floor are also visible. Alongside the ruins, an artifact-filled museum chronicles Conímbriga's Iron Age origins, its heyday as a prosperous Roman town, and its decline after the 5th-century barbarian conquests.
