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.
History
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:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
