High Quality Content by WIKIPEDIA articles! St Mark`s Church is an ancient small church on the north-east side of College Green, Bristol, England, built c. 1230. Better known to mediaeval and Tudor historians as the Gaunt`s Chapel, it has also been known within Bristol since 1722 as the Mayor`s Chapel. It is the only church in England privately owned and used for worship by a city corporation. It was built as the chapel to the adjacent Gaunt`s Hospital, now demolished, founded in 1220. Except for the west front, the church has been enclosed by later adjacent buildings, although the tower is still visible. The church contains some fine late gothic features and a collection of continental stained glass. It is designated by English Heritage as a grade I listed building.
