Itanos was particularly powerful community during the Greek era and it was flourishing by the seventh century BC. Itanos was continuously at war with its neighbours Praisos, and later Hierapytna.
In the 8th century AD Itanos was destroyed in an earthquake but the inhabitants stayed and rebuilt the town. Only in the 15th century after attacks by pirates the town was finally destroyed and deserted. Because the west of Crete slowly elevates upwards and the east odf the island is slowly sinking (6 to 9 meters in the last 2000 years, mainly caused by earthquakes) parts of the harbour of Itanos have now sunk into the sea.
Herodotos was the first Greek historian who mentioned Itanos. The archeological site of Itanos is open to the public. It is possible to see the ruins of houses, city walls and Christian churches. Many Greek inscriptions were found in situ; the most famous one, kept now in the monastery of Toplou, relates a decision by the Roman Senate about Itanos' conflicts and territorial disputes with the neighbor cities Praisos and Hierapytna.
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.
