Southwark Cathedral

Tucked between Borough Market and the railway viaduct at the southern end of London Bridge, Southwark Cathedral is the oldest Gothic church building in London, on a site that has held a church for over a thousand years. The priory of St Mary Overie was founded here in 1106, and the church that stands today was begun after a fire in the 1220s. It became the cathedral of the new diocese of Southwark in 1905, having spent the centuries in between as the parish church of St Saviour.

The square central tower, with its four pinnacles, is what shows above the roofs of Borough, and it has a hard job of it now, standing directly beneath The Shard. That contrast is what makes it worth finding: a small Gothic tower in a sea of railway lines and market roofs.
