London’s Alleys: St Chad’s Place, WC1

This is a nice passageway in King’s Cross that leads from a covered entrance through to a cobbled (setts) alley, above a railway and ends in an ornately decorated building.St Chad’s Place first shows up as the area is being developed in the late 1700s as a part-built road called  Field Street.

It may have been renamed shortly afterwards as the area built up, as it shows up just 30 years later, possibly called something like Fifteentract Lane.
