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:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
