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:Monte d"Accoddi is a Neolithic archaeological site in northern Sardinia, located in the territory of Sassari. The site consists of a massive raised stone platform thought to have been an altar. It was constructed by the Ozieri culture or earlier, with the oldest parts dated to around 4,000–3,650 BC.
The site was discovered in 1954 in a field owned by the Segni family. No chambers or entrances to the mound have been found, leading to the presumption it was an altar, a temple or a step pyramid. It may have also served an observational function, as its square plan is coordinated with the cardinal points of the compass.
The initial Ozieri structure was abandoned or destroyed around 3000 BC, with traces of fire found in the archeological evidence. Around 2800 BC the remains of the original structure were completely covered with a layered mixture of earth and stone, and large blocks of limestone were then applied to establish a second platform, truncated by a step pyramid (36 m × 29 m, about 10 m in height), accessible by means of a second ramp, 42 m long, built over the older one. This second temple resembles contemporary Mesopotamian ziggurats, and is attributed to the Abealzu-Filigosa culture.
Archeological excavations from the chalcolithic Abealzu-Filigosa layers indicate the Monte d"Accoddi was used for animal sacrifice, with the remains of sheep, cattle, and swine recovered in near equal proportions. It is among the earliest known sacrificial sites in Western Europe.
The site appears to have been abandoned again around 1800 BC, at the onset of the Nuragic age.
The monument was partially reconstructed during the 1980s. It is open to the public and accessible by the old route of SS131 highway, near the hamlet of Ottava. It is 14,9 km from Sassari and 45 km from Alghero. There is no public transportation to the site. The opening times vary throughout the year.
