A dig has revealed “one of the largest” temple buildings in Roman Britain.
The 2nd Century temple site at Caistor St Edmund, near Norwich, has been known about since 1957, but its true scale has only just emerged.
Archaeologist Prof Will Bowden said its size, 20m by 20m (65ft by 65ft), showed “how important this cult was to the Iceni”.

Prof Bowden, the project director, said the post-excavation process had since been completed and this “confirmed that we were looking at a building that was exceptional”.
He said it was “one of the largest of its type in Roman Britain” which “indicates not only the importance with which the site was regarded but also that the Iceni had the resources to construct major public buildings should they choose to”.

Caistor was the site of Venta Icenorum, the smallest Roman regional capital in Britain.
Its forum – the main public building – was less than a quarter of the size of Verulamium, now known as St Albans.
Historians saw its small scale as a sign of the Iceni’s impoverishment after Queen Boudicca led the Iceni tribe against the Romans.
But Prof Bowden said: “They had the resources to construct major public buildings should they choose to.”
