Dragon Bowl

A small museum, The City Wall at Vine Street, has opened in the basement of a new building on Vine Street in the City of London ( The entrance is actually in Jewry Street). 
It's based around a section of Roman wall and bastion and also has a display of archaeological objects recovered on the site. 
This is a late 1600s Chinese porcelain bowl, found in a cesspit with other broken plates.
The museum is free to visit, but you have to pre book. The website is here.
