Nesactium was an ancient fortified town and hill fort of the Histri tribe. In pre-Roman times, Nesactium, ruled by its legendary king Epulon, was the capital of the tribal population of the peninsula called Histri, who were also connected to the prehistoric Castellieri culture. Some theories state a later Celtic influence, but who they were and where they came from has never been discovered for certain. It is believed that their main economic activities were trade and piracy all over the ancient Mediterranean Sea.
In 177 BC, the town was conquered by the Romans and destroyed. Rebuilt upon the original Histrian pattern, it was a Roman town until 46–45 BC, when the Ancient Greek colony Polai was elevated to Pietas Iulia, today Pula. The town was located on the ancient road Via Flavia, which connected Trieste to Dalmatia. The area was abandoned by the Romans in the 6th century, following the Slav invasions.
At the end of the fourth century, the walls were renewed. Two churches were added, next to each other, between the bathhouse and the forum. The southern one, the largest, was probably dedicated to Mary and used for the daily ceremonies; the northern one was used for baptisms and religious ceremonies. There are traces of fire, which may have something to do with the Avar attacks on Histria in 600 and 611.References:
Castle Rushen is located in the Isle of Man"s historic capital, Castletown. The castle is amongst the best examples of medieval castles in the British Isles, and is still in use as a court house, museum and educational centre.
The exact date of castle is unknown, although construction is thought to have taken place during the reigns of the late 12th century and early 13th century rulers of the Isle of Man – the Kings of Mann and the Isles. The original Castle Rushen consisted of a central square stone tower, or keep. The site was also fortified to guard the entrance to the Silver Burn. From its early beginnings, the castle was continually developed by successive rulers of Mann between the 13th and 16th century. The limestone walls dominated much of the surrounding landscape, serving as a point of dominance for the various rulers of the Isle of Man. By 1313, the original keep had been reinforced with towers to the west and south. In the 14th century, an east tower, gatehouses, and curtain wall were added.
After several more changes of hands the English and their supporters eventually prevailed. The English king Edward I Longshanks claimed that the island had belonged to the Kings of England for generations and he was merely reasserting their rightful claim to the Isle of Man.
The 18th century saw the castle in steady decay. By the end of the century it was converted into a prison. Even though the castle was in continuous use as a prison, the decline continued until the turn of the 20th century, when it was restored under the oversight of the Lieutenant Governor, George Somerset, 3rd Baron Raglan. Following the restoration work, and the completion of the purpose-built Victoria Road Prison in 1891, the castle was transferred from the British Crown to the Isle of Man Government in 1929.
Today it is run as a museum by Manx National Heritage, depicting the history of the Kings and Lords of Mann. Most rooms are open to the public during the opening season (March to October), and all open rooms have signs telling their stories. The exhibitions include a working medieval kitchen where authentic period food is prepared on special occasions and re-enactments of various aspects of medieval life are held on a regular basis, with particular emphasis on educating the local children about their history. Archaeological finds made during excavations in the 1980s are displayed and used as learning tools for visitors.
