Sa Portella

The first city wall was built by the Romans, probably around 400. This was almost completely destroyed by the Vandals around 430 AD. Some 500 years later, the Moors built a new one on the remains of the Roman wall, which was expanded in the 11th century.
When pirate attacks increased in the Middle Ages, it was decided in 1575 to strengthen and expand the existing, almost 700 year old walls. It took 226 years to complete. Completed in 1801, demolition began again in 1902. It lasted almost 30 years and wasn't complete.
Sa Portella, in English "the little gate", dates from the time of the Moors. The coat of arms, however, is that of the Aragonians. In the course of time, the name of the törchen was transferred to the entire district behind it.
