The cheranmahadevi page uses its exact OpenStreetMap town node. Each destination was assigned to the itinerary before its road route was measured.
Keep worship and history distinct
Temple tradition is identified as tradition. Dated patronage, architecture and modern transport belong to separate evidence and are not blended into one claim.
Make the practical plan
Confirm split worship hours, carry water, save the return point offline and agree taxi waiting time before leaving the centre.
Access is specific
A road approach does not prove step-free entry. Ask about parking, gradients, thresholds, seating, toilets and photography at the site.
