Once upon a time,
before the town of Portsmouth was founded, this coastline was made up of creeks, low-lying marsh and water. Over the centuries the coastline has altered, but the town's position here on the south coast, its proximity to the open sea, coupled with control of the harbour and its entrance, have secured Portsmouth's place in history as one of the world's great anchorages and a rendezvous for British shipping in times of war for over 800 years.
