Britain's most ancient fishing trap has been discovered while a strange underwater shape was spotted from a plane flying overhead.This millennium old archeo-site is located beside Popit sand beach near the Teifi estuary, near Cardigan, West Wales the coastline.
Research carried out on Google Earth.The place is discovered at March, 2009.
The 853ft (260m) long construction is thought to have been built 1,000 years ago,around the time of the the Norman Conquest and designed to trap fish behind rock walls.The trap is believed to have been made from locally quarried rock, or possibly boulders carried in by glaciers during the last Ice Age.
Archeologists believe large numbers of people worked together to erect this long rock-built contraption and it allowed them to catch plentiful numbers of fish for their supper. The discovery has given them a fascinating glimpse into how medieval communities survived through hunting and fishing.
Fish swam into the estuary but became trapped by the outgoing tide before being hooked out using nets.
