Lohja church is the third biggest medieval church in Finland. It dates back to the 15th century, probably between years 1470 and 1490. Impressive chalk paintings inside the church are made in the regime of bishop Arvid Kurki (1510-1522).
The Lohja parish was established in 1230s or 1240s and there have been several wooden churches before the present one. Also origins of the bell tower date back to the Middle Ages. The upper part was added in 1740.
The church site is named as the national built heritage by National Board of Antiques.
Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
