Järppilä manor was first mentioned in the 1480s. Bertil Ivarsson Grön acquired Järppilä in 1567 and since him the chain of manor owners is uninterrupted. The manor has been owned by famous Horn and Fleming noble families.
The original main building was a three-storey manor-castle built in the 1570s. It was destroyed in the was between Duke Charles and King of Sweden Sigismund (1597–1599). Today only a small tower remains and is restored as a magazine.
The basement of the present Järppilä manor house was probably built in the 17th century. The empire style building was completed to the present appearance in the 1830s. Järppilä has been held by the current family since 1898. Today it offers event and wedding services.
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.
