Building houses on a flood plain is always a contentious issue, especially after what happened on the Somerset Levels last winter, but it's nothing new. Archaeologists have been looking at a site at Glastonbury where they did just that, more than 2000 years ago.
Glastonbury Lake Village was built on a man made island in the wetlands and it's been very well preserved.
Archaeologists Bob Croft and Richard Brunning told us more:
Archaeologists have been digging at the site of a 2,200 year old Iron Age settlement in Somerset.
Glastonbury Lake Village is one if Britain's best preserved sites from the era. It was last excavated over a hundred years ago.
The Glastonbury Festival is up and running. 175 thousand people are expected to descend on Michael Eavis's famous farm over the next three days.
As ever, one of the big talking points will be the weather and there is a threat of heavy showers over the Pilton site in the next 24 hours or so.
Our Somerset Correspondent David Woodland, who has experienced many festivals, will be enjoying - and enduring - the festivities along with everyone else.
