The Topana fortress is located near to the mountain slopes of Modro jezero (Blue lake) and dominates over the town. The fortress was built in the 10th century and throughout history had a great strategic significance. The patron of the Imotski border- land is Our Lady of the Angels, and a small church of the same name is located in the fortress' surroundings. The fortress was under Ottoman rule for over 200 years. Today, this fortress is a favourite place thanks to the extraordinarypanoramic view, and many cultural events are held here during the summer.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.
