The Annexe space focuses on the pottery discovered at the Roman town of Calleva near Silchester.
Around 200 pieces are displayed, highlighting their variety and beauty, and also the impressive scale of the Victorian excavations.
Photographs of the early Silchester excavations can also be seen in the Annexe, including images of the pots you can now see on display.
There is seating in the Annexe and a selection of books for adults and children, which you can look at while you're resting your feet!
One of our largest pieces is a decorated storage jar known as the Jubilee Pot because it was found on the day of Queen Victoria's Diamond Jubilee in 1897.
