Las Ruinas de la antigua Ciudad Romana de Pollentia are the largest Roman archaeological site found in Mallorca. They are located between Bahía de Pollensa and Bahía de Alcudia, particularly outside the medieval walls of the historic center of Alcudia.

The Roman City of Pollentia near the present city of Palma was founded by the consul Quintus Caecilius Metellus, head of the Roman expedition that dominated the island in 123 B.C.
In Roman times, Pollentia was the capital of the Balearic Islands. It is an archaeological site of great historical value where we can see several important public buildings. Beside the old town of Alcudia you will see historical ruins in the area outside its walls. The Roman City of Pollentia occupies an area of 12 hectares. The archaeological site includes barrio de La Portella, where you can see some streets and buildings of the time, part of the walls of 100m in length, the Forum, and on the outskirts of the city is the Roman theater that had with a capacity of up to 2,000 people.

There is evidence that this site dates from the sixteenth century, but it was not until the twentieth centurywhen excavations started that allow us to enjoy the Roman City of Pollentia as we see it today. In the excavations, many objects were found, but some pieces particularly valuable as coins and a girl head bronze give us a clue about the importance of old town of Pollentia, a rich and refined town, connected and linked economically to Rome, Hispania and North Africa.
