Each stone head is up to one metre square and weighs almost a tonne
Seven and a half newly sculpted angel heads are being exhibited at Salisbury Cathedral to celebrate the building's 750th anniversary.
Each head represents a century of the cathedral's history and has been designed by sculptor, Emily Young.
They will be placed in three different locations and are carved from the same Purbeck stone as the cathedral.
Ms Young also sculpted the "Lunar Disc" which has been located in Cathedral Close since 2004.
Canon treasurer Mark Bonney, of Salisbury Cathedral, said: "It is a great honour for us that Emily has sculpted these new and truly powerful angel heads to exhibit here.
"Through her art these heads represent for us a deep sense of spirituality, humanity and optimism and we expect many a photographer to take on the challenge of picturing their magnificent reflections in our new font."
The four largest heads will be placed in the main nave, two more will be situated in the Trinity Chapel and one and a half will be found in the cloisters facing the cathedral's spire.
Each stone head is up to one metre square and weighs almost a tonne.
The exhibition will run until 9 February 2009.
