The Church of St Teilo is the parish church of Llantilio Pertholey. The church is thirteenth century in origin with significant additions in the sixteenth century, a major restoration in 1890 and further minor restoration in the twentieth century. The tower is of the early fourteenth century and the aisle of slightly later date. Around the chancel are three chantry chapels. The bell tower holds six bells, dating from the seventeenth century.
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.
