Guarded by a medieval building, four temple columns bear witness to the magnificent origins of Barcelona in the heart of the Gothic Quarter. These columns are all that remains of the Temple of Augustus. They can be found at the end of Carrer Paradís in the Gothic Quarter.

The temple was built in the 1st century BC and, as its name suggests, it was dedicated to the worship of Emperor Augustus. The temple was reconstructed by the architect Puig i Cadafalch in the early 20th century.
