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 Broch of Gurness is an Iron Age broch village. Settlement here began sometime between 500 and 200 BC. At the centre of the settlement is a stone tower or broch, which once probably reached a height of around 10 metres. Its interior is divided into sections by upright slabs. The tower features two skins of drystone walls, with stone-floored galleries in between. These are accessed by steps. Stone ledges suggest that there was once an upper storey with a timber floor. The roof would have been thatched, surrounded by a wall walk linked by stairs to the ground floor. The broch features two hearths and a subterranean stone cistern with steps leading down into it. It is thought to have some religious significance, relating to an Iron Age cult of the underground.
The remains of the central tower are up to 3.6 metres high, and the stone walls are up to 4.1 metres thick.
