Heritage walk: the fort at first light

The 6 am walking group meets at the gate with the punctuality of people stealing something — in this case, an hour when the monument is only architecture and birdsong, before it becomes a destination.

The retired archaeologist who leads the walk narrates the fort as a construction site rather than a postcard: where the quarries were, why the ramp curves against cavalry, which repairs are Mughal, which are British, and which are last decade's cement, delivered with a sigh.

First light does the guiding for him. The red sandstone goes through five colours in forty minutes, the carvings throw shadows that flatten by eight, and the group photographs details that midday visitors walk past — mason's marks, a sundial, one carved parrot nobody can explain.

By seven-thirty the queue is forming outside and the group disperses with the smugness of early risers everywhere. The archaeologist stays a moment longer, patting a wall the way one greets an elderly relative, and follows them out through the crowd arriving to see what he just showed them empty.
