Conimbriga Roman Ruins - Coimbra, Portugal

This is the place to see the best preserved Roman ruins in Portugal. Romans settled in Conimbriga between 1^st and 3^rd centuries AD. I recommend to go during the week as there are two buses coming and going to and from Coimbra; there is only one bus on the weekends, and it is possible to see all in half day. There are very well preserved mosaics from the 2^nd and 3^rd centuries. If you happen to be an European resident and are less than 26 years of age, you would pay a very discounted ticket.
