By enlarging the photo it is possible to read the two notices on the column
on the right.
The rectangular one says “REG-VI-Ins-VI”, short for Regio 6 Insula 6 - loosely
translated as Region 6 Block 6,
which corresponds to the markings on the Pompeii street map. The notice with the ‘arrowed’ sides
is difficult
to decipher, but it is probably “Vicolo Della Fullonica”. The camera is pointing
roughly west.
In 1943 a bomb fell near here causing further destruction to the buildings.
