She explained: “We were able to establish that it was an articulated burial, that is one which had not been disturbed before.”
She said pottery found in the area suggested it was a medieval grave.
The grave has been covered up but further archaeological work on the grave and the site will continue.
Mrs King, director of Foundations Archaeology, said: “More interestingly we have uncovered parts of a medieval wall which can still be seen.”
Area Dean of Reading, Canon Brian Shenton, in charge of Reading Minster of St Mary the Virgin – one of the town’s few Grade I-listed buildings – had hoped the skeleton would prove to be both Saxon and female.
He said: “There was a convent on the site in Saxon times before the Minster was built and that might have meant the skeleton was one of the nuns.”
