St Cynfelin (also known as St Matu) is reputed to be the founder of St Mary's Church in Welshpool, during 'the age of the saints in Wales' in the 5th and 6th centuries.
The church was originally built c. 1250, but only the lower courses of the tower now remain from that date. The current building is largely as rebuilt or restored in 1871 by George Edmund Street. The nave was rebuilt in the 16th century, and with the whole building was substantially restored in 1871.
The 15th century chancel ceiling may have come from Strata Marcella Abbey, about five miles away, and a stone in the churchyard is said to have been part of the abbot's throne. A memorial in the church commemorates Bishop William Morgan, translator of the Bible into Welsh, who was the vicar from 1575 to 1579.
The churchyard contains seven Commonwealth war graves, of five British soldiers of World War I and a soldier and airman of World War II.
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.
