"The spire of Chichester Cathedral, rising above its green copper roof, can be seen for many miles across the flat meadows of West Sussex and is a landmark for sailors, Chichester being the only medieval English cathedral which is visible from the sea."

In 1861 the spire collapsed; it was rebuilt by 1866. Bizarrely, the rubble from the collapsed spire was used to build Spire Cottage in Hunston, Chichester - and we have stayed in this B&B.
