The highest point in Roman Barcelona is marked with a circular millstone at the entrance to the Centre Excursioniste de Catalunya, a club dedicated to exploring the mountains and highlands of Catalonia on foot and on skis. Inside the entryway on the right are some of the best-preserved 1st- and 2nd-century Corinthian Roman columns in Europe. Massive, fluted, and crowned with the typical Corinthian acanthus leaves in two distinct rows under eight fluted sheaths, these columns remain only because Barcelona's early Christians elected, atypically, not to build their cathedral over the site of the previous temple. The Temple of Augustus, dedicated to the Roman emperor, occupied the northwest corner of the Roman Forum, which coincided approximately with today's Plaça Sant Jaume.
