Arch of Caracalla

The Triumphal Arch of Caracalla in Volubilis was erected in 217 CE at the intersection of the Decumanus Maximus (east) and the Porte à trios baies (west) which led to the forum. The arch was constructed with compact limestone from the nearby Mount Zerhoun. The front of the monument consists of a single arch, framed by two massive piers, each adorned with two pairs of pedestals that originally supported Corinthian columns. Between the columns are niches that functioned as fountains that poured water into basins below. Above the alcoves are tondos, within which some figures are hotly contested; some propose that the figures are members of the imperial family personified as the seasons while others propose that they are nymphs. An inscription lies on the arch's eastern facade, which is the main source of information for the construction, and claims that the arch was topped with a chariot drawn by six horses in bronze. The Lisbon earthquake of 1775 nearly destroyed the arch, but in the 1930s the French reconstructed it by utilizing drawings from the English travelers Henry Boyde and John Windus thirty years before the seismic event.
