Aquincum was an ancient city, situated on the northeastern borders of the Pannonia province within the Roman Empire. The ruins of the city can be found today in Budapest. It is believed that Marcus Aurelius may have written at least part of his book Meditations at Aquincum.
It was originally settled by the Eravisci, a Celtic tribe. Aquincum served as a military base (castrum), having been part of the Roman border protection system called limes. Around AD 41-54, a 500-strong cavalry unit arrived, and a Roman legion of 6,000 men was stationed here by AD 89. The city gradually grew around the fortress, and after Pannonia was reorganised by the Romans in AD 106, Aquincum became the capital city of Pannonia Inferior. The city had around 30,000 to 40,000 inhabitants by the end of the 2nd century, and covered a significant part of the area today known as the Óbuda district within Budapest. Ruins from the old Roman settlement can be seen in other parts of Budapest as well, notably Contra-Aquincum. These Roman structures were, during the 2nd and 3rd century AD, the heart of the commercial life of the Pannonia province. The excavations show evidence of the lifestyle of this period. The most important monuments in Aquincum are the two amphitheaters the Aquincum Civil Amphitheatre and the Aquincum Military Amphitheatre built in the 1st century AD.
People living in the settlement could enjoy the achievements of the Empire, like central heating in the houses, public baths, a Mithraeum and palaces, as well as two amphitheatres, the Aquincum Civil Amphitheater and the larger Aquincum Military Amphitheatre for gladiatorial combats and beast fights.
Many historic artifacts from the city now appear in the Aquincum Museum. The museum exhibits a reconstruction of the hydraulic system, Roman houses and paintings that have been recovered on site. The ruins of a three-level aqueduct have been discovered around the city.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
