Sion is a small castle ruin in Chlístovice in the Central Bohemian Region of the Czech Republic. It lies near Kutná Hora. It was founded between 1426 and 1427 by Hussite Jan Roháč of Dubá. After a successful four-month siege the castle was conquered and burned by Emperor Sigismund's allies in 1437. Today, only scattered parts of the basement stone walls with some arches and stairs remain of the original castle.
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.
