Conímbriga is one of the largest Roman settlements excavated in Portugal and was classified as a National Monument in 1910. It is 16 kilometres from Coimbra and lies within the civil parish of Condeixa-a-Velha and Condeixa-a-Nova.

Conímbriga is a walled urban settlement consisting of various structures such as a forum, basilica and commercial shops, thermal spas, aqueducts, insulae (a kind of apartment building for the ordinary townspeople), homes including beautifully preserved mosaic floors and domus (houses owned by the upper classes and wealthy) such as the Casa dos Repuxos and Casa de Cantaber), in addition to the paleo-Christian basilica.

A visitors’ centre (which includes restaurant/café and gift-shop) was constructed to display objects found by archaeologists during their excavations, including coins, surgical tools, utensils and ceramics.
