The Rua Augusta Arch was built to commemorate the city's reconstruction after the 1755 earthquake. It has six columns (some 11 m high) and is adorned with statues of various historical figures. Significant height from the arch crown to the cornice imparts an appearance of heaviness to the structure. The associated space is filled with the coat of arms of Portugal. The allegorical group at the top, made by French sculptor Célestin Anatole Calmels, represents Glory rewarding Valor and Genius.
Originally designed as a bell tower, the building was ultimately transformed into an elaborate arch after more than a century.
Because of the top cornice's great height, the figures above it had to be made colossal. The female allegory of Glory stands on a three-step throne and holds two crowns. Valor is personified by an amazon, partially covered with chlamys and wearing a high-crested helmet with dragon patterns, which were the symbols of the House of Braganza. her left hand holds the parazonium, with a trophy of flags behind. The Genius encompasses a statue of Jupiter behind his left arm. At his left side are the attributes of writing and arts.
The four statues over the columns, made by Victor Bastos, represent Nuno Alvares Pereira and Sebastião José de Carvalho e Melo, Marquis of Pombal on the right, and Vasco da Gama and Viriatus on the left. The two recumbent figures represent the rivers Tagus and Douro.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
