This yellow-painted PROV GAS CO gas utility cover is seen in the cracked sidewalk of the street beneath our feet.
The Providence Gas Company was chartered in 1847 and began operations in 1848, making coal gas for lighting. In the 2000s, it went through several corporate acquisitions; the original name is no longer used.
Two of its former buildings are listed in architecture guides of Providence: the Providence Gas Company Purifier House (more here and here) on Allens Avenue and the Providence Gas Company Building (more here) on Weybosset Street.
