It is hard to believe that under this depressing mound of litter lies an important historical site.
There, buried under the grime and grot, is nothing less than the late-Roman tomb of a wealthy Christian family, dating from around 400 AD, containing two sarcophagi and decorated with frescoes of roses, wreaths, swags and peacocks.
The frescoes are similar to those in the catacombs of San Giovanni, where 4th century Christians took refuge from persecutors.
The mausoleum is in Viale Teocrito in Syracuse, only a few steps from the famous Paolo Orsi archaeological museum, but no visitors would know it was there because it has sunk virtually without trace, surrounded by grim corporation railings.
Over the years, the roads have been gradually raised around it, leaving it a good two metres below street level, as if it is some eyesore public toilet block.
Now, the traffic roars and blasts its way past above roof height, while buses that stop almost beside it carry passengers who afford it not a glance. It is opposite one of the entrances to the modern sanctuary, the Madonna delle Lacrime, yet I doubt that more than a handful of worshippers would be aware of its existence.
Those who do know about it are anxious for its value and historical significance to come to wider notice and to be accorded more TLC.
The mausoleum is named after Vincenzo Politi, the painter, antiquarian and archaeologist who discovered it in 1826. If he knew what a grim state his lovely discovery was in, he might be spinning in his own grave.
