Opposite the southeast end of La Catedral, narrow Carrer del ParadÃs leads towards Plaça de Sant Jaume. Inside No 10, an intriguing building with Gothic and baroque touches, are four columns and the architrave of Barcelona’s main Roman temple, dedicated to Caesar Augustus and built to worship his imperial highness in the 1st century.
You are now standing on the highest point of Roman Barcino, Mont TÃ ber (a grand height of 16.9m).
