As a kid my class was taken on a school day trip to Silchester, a wonderful Roman town we were told, so interesting.
That is the forum, where everybody met, discussed and decided.
I saw a grassy mound.
That is the amphitheatre, for plays, big events and entertainment.
I saw a duck pond.
Here is the wonderful exhibition of Roman artifacts.
I saw a shed full of pottery shards.
