Somewhat vague item from UKTV:

A series of ancient paintings have been uncovered beneath the streets of London.

The Roman artworks were found underneath an Italian restaurant in Lime Street, in the City of London.

Painted 1,900 years ago, the paintings depict goldfinch and lavish bunches of grapes, magazine London Archaeologist reports.

Experts believe that they were painted for a wealthy Roman's home, as the area around Lime Street used to the most prestigious address in Roman London.

Archaeologists are hailing the find as one of the most significant of recent decades and hope that the whole set of paintings, damaged in a building fire, can be reconstructed.
