The Naantali Church was originally part of the Catholic Convent of St. Bridget. The convent was built between years 1443 and 1462 and church probably later in the end of 15th century. Nowadays the church is the only remaining building of the convent, which was closed during Reformation in 1540s. Naantali Church is damaged several times by fire and the present interior is mostly from the modern times except the pulpit (1622) and artefacts. There are lot of medieval items in church, for example crucifix from the monastery, wooden statues and magnificent altarpiece.
The church is situated in the old town of Naantali, which is mostly built in the 18th and 19th centuries. Finnish National Board of Antiquities has named the church and old town area as national built heritage.
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.
