Đurđevac castle and old town was built by the Bishop of Pécs, most probably around 1488. The town, or fort, was built on high ground in the middle of a swamp to the north of the town of Đurđevac in Croatia, because of the threat of the Turkish, and constant conflicts between the nobility. The height of the tower is aroun 9 m.
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.
