The Kirna estate was given as a gift to the von Fersen family in 1614 and remained in the ownership for over a hundred years. After 1787, it belonged to various Baltic German and Russian families from the nobility. After 1919 it was used as a school up until World War II. During the Soviet occupation of Estonia, the manor housed the offices of a collective farm. Today it stands in private ownership and is used for it's energetically propitious place as spa.
The building received its present appearance during a neoclassical reconstruction of an earlier building around 1820. The hall and other ceremonial rooms on the main floor was at that time also decorated with typical stucco ornaments. Some later additions were in a neo-Gothic style. The family cemetery of the von Osten-Sacken family together with the ruins of a funeral chapel reminding one of an antique temple are located near the centre of the estate.References:
La Hougue Bie is a Neolithic ritual site which was in use around 3500 BC. Hougue is a Jèrriais/Norman language word meaning a \'mound\' and comes from the Old Norse word haugr. The site consists of 18.6m long passage chamber covered by a 12.2m high mound. The site was first excavated in 1925 by the Société Jersiaise. Fragments of twenty vase supports were found along with the scattered remains of at least eight individuals. Gravegoods, mostly pottery, were also present. At some time in the past, the site had evidently been entered and ransacked.
In Western Europe, it is one of the largest and best preserved passage graves and the most impressive and best preserved monument of Armorican Passage Grave group. Although they are termed \'passage graves\', they were ceremonial sites, whose function was more similar to churches or cathedrals, where burials were incidental.
