Conímbriga, an ancient city of Lusitania, is the most impressive Roman complex in Portugal, a place where history still breathes among its baths, forum, amphitheater, and uniquely delicate mosaics, such as those in the famous House of Fountains. Although only a small part has been excavated, the grandeur the city held throughout its almost six centuries under Roman rule is evident. The second wall, hastily erected with stone taken from entire buildings, reveals a time of threat and decline, a prelude to the abandonment that followed the Suebian invasions. Today, among fallen columns and pavements that still gleam in the sun, Conímbriga continues to intrigue and amaze, preserving in its ruins the stories that time has almost erased.

Cominbriga, a space where we can get an idea of what it was like to eat in times gone by. Learn from the past to better live in the present.👍

Second week June 2025, not a single drop of water on the river. Seems the river only have water during winter season.

The route is very pretty, surrounded by trees in the first half of the journey. However, we went in February and the river was practically empty. There is no trace of the falls.

The path is very nice to walk and can be combined with a visit to the ruins. But be careful: the river only has water between November and March. We were there in May and didn't see a drop of water. So no waterfall either.

A visit to the museum is worthwhile.
