St.Andrews harbour at low tide

In the background one can see the Cathedral of St Andrew (often referred to as St Andrews Cathedral). It is a ruined Roman Catholic cathedral in St Andrews, and was built in 1158 and became the centre of the Medieval Catholic Church in Scotland as the seat of the Archdiocese of St Andrews and the Bishops and Archbishops of St Andrews. It fell into disuse and ruin after Catholic mass was outlawed during the 16th-century Scottish Reformation. It is currently a monument in the custody of Historic Scotland. The ruins indicate that the building was approximately 119m (391 feet) long, and is the largest church to have been built in Scotland.
One can a;so see St Rule's tower located in the Cathedral grounds This tower predates the cathedral, having served as the church of the priory up to the early 12th century. The building was retained to allow worship to continue uninterrupted during the building of its much larger successor.
The views from the top are wonderful.
