Taivassalo Church is the oldest of the three medieval stone churches in Finland that are dedicated to the Holy Cross. The construction of the church is believed to have begun between the years 1425 to 1440. In 1460s, the third aisle was built and the inner walls were decorated with new murals. It was the first time in Finland that frescos were painted to nearly all important surfaces of a church by a group of professional artists.
The medieval altarpiece as well as wooden sculptures of Taivassalo Church were donated to The National Museum of Finland in 1890. However, Taivassalo Church still has a magnificent triumph crucifix above the altar, in front of the chancel window. This crucifix is one of the oldest and best preserved crucifixes in Finland. The rococo front of the organ, which is unusual by Finnish standards, has remained intact ever since 1767 although the organ has been replaced several times.
As a whole, the church with its murals looks much the same as it would have looked at the end of the Middle Ages.
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.
