St. Paraskevi Church in Radruż dates from the sixteenth-century, which together with different tserkvas is designated as part of the UNESCO Wooden tserkvas of the Carpathian region in Poland and Ukraine.
The tserkva belongs to the oldest and best kept wooden sacramental architecture tserkvas in Poland. Part of the prestigious World Monuments Fund (WMF) list of buildings worthy of preservation and financial sponsorship.
The tserkva is located on an oval hill, by the Radrużka stream, and together with the bell tower is surrounded by a wall (existent from 1825), with a fortification structure. The tserkva's structure is constructed out of a fir and oak framework. The tserkva was most likely funded by poseł to Sejm, and starosta Jan Płaza (died 1599). While being used for sacramental services, the tserkva was also used as a fortress against the invasions by the Tatars.
References: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.
