Laiuse Castle was the first castle in Estonia built to cope with firearms. The oldest part of the castle was probably built in the end of 14th century by the Livonian Order. It was first mentioned in 1406. In 1558 during the Livonian War the castle was conquered by Russian troops and badly damaged. Nonetheless the castle was later still in use both by Polish and Swedish rulers. During the Great Northern War, from 1700 to1701, after the Battle of Narva, the Swedish king Charles XII established his winter quarters here. For five months Laiuse was the administrative center of Swedish Empire.
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.
