Hinterburg is one of the four castles in a string along the Neckar River, built by the von Steinach family in the 1100s. It is the oldest of the four, serving a strategic purpose in allowing the lords to observe the Neckar and Steinachtal. One of the earliest records mentions Bligger von Steinach, c. 1160. His son, Bligger II, who was also a famous minstrel of the time, added much of the outer wall that helped drastically improve the castle's defensive posture. At one time it also had a dry moat with a drawbridge. The castle continued to be used up until the 1600s, largely in the service of the Elector Palatine. Afterwards it began to decay from neglect as it lost its importance in the era of cannon. There is no indication that it was ever seriously besieged.References:
The Broch of Gurness is an Iron Age broch village. Settlement here began sometime between 500 and 200 BC. At the centre of the settlement is a stone tower or broch, which once probably reached a height of around 10 metres. Its interior is divided into sections by upright slabs. The tower features two skins of drystone walls, with stone-floored galleries in between. These are accessed by steps. Stone ledges suggest that there was once an upper storey with a timber floor. The roof would have been thatched, surrounded by a wall walk linked by stairs to the ground floor. The broch features two hearths and a subterranean stone cistern with steps leading down into it. It is thought to have some religious significance, relating to an Iron Age cult of the underground.
The remains of the central tower are up to 3.6 metres high, and the stone walls are up to 4.1 metres thick.
