The Castillo de San Julián was built between the 18th and 19th centuries, incorporating a tower which had been built by the British in 1706. The fort remains intact today, but it is in a rather dilapidated state.
The Castillo de San Julián is located on and takes its name from the Monte de San Julián. In 1706, the British captured Cartagena during the War of the Spanish Succession, and they built a cylindrical tower on the hill. Following the end of the war, the Spanish began to build a fort on the hill in order to protect the mouth of Cartagena's harbour. The new fort incorporated the British tower, and construction took a very long time, being completed in 1883.
The fort was used as a military prison during the Spanish Civil War.
Today, the fort is still intact but it is in a rather dilapidated state. It is listed on the Bien de Interés Cultural, and is currently owned by Telefónica, who have installed a number of antennas within the fort. The city administration is attempting to acquire and restore the fort.
The Castillo de San Julián is essentially a bastioned fort, but it also contains tenailles and caponiers, which are typical of polygonal forts. It is built in neoclassical architecture.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.
