Sanctuary of Heracles was a large paved court surrounded by buildings on three sides and with the principal altar in the centre. It wouldn’t have been as separate from the rest of the town as many sanctuaries, and would have been part of the town’s landscape, immediately apparent to the citizens. The 5th century re-buildings were on a much larger scale than the original 6th century rooms.
As you stand at the gate of Silenus, at the entrance to the sanctuary, the temple of Heracles is at the opposite end, at the very North -it would have been on a raised platform. Originally, it was just a single chambered naos, but was later embellished with a wide colonnade on all sides, giving it a square form, slightly different from the traditional rectangular temples, but the colonnade on all sides is very traditionally Greek.
To the west and at the front of this temple was the stepped and porched entrance to the temenos – this was the last addition to the sanctuary, in the 2nd century BC. It opened onto a paved court with the stepped altar in its centre, and a long gallery hall forming the opposite border (along to the right from the entrance at the gate of Silenus).
The South side was occupied by a porticoed building containing official administrative offices for the sanctuary and the banqueting rooms – where the important early summer feast the Heracleia was celebrated.
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.
