Heritage Development Plan for Tiruchendur: A Framework for Delineating and Planning a Pilgrimage Heritage Town

Tamil Nadu protects 38 heritage towns through a single height rule, and that rule alone cannot guide how these towns grow. This paper asks what a proper Heritage Development Plan (HDP) needs, using Tiruchendur, a coastal pilgrimage town with no HDP or master plan, as its test case. We review the principles and tools used in heritage planning, namely the Historic Urban Landscape (HUL) approach, Heritage Impact Assessment (HIA), participatory planning and conservation-based zoning. We then compare how nine Indian towns and one Norwegian programme have drawn the boundary of their plan areas, since that choice shapes everything that follows. The comparison shows two workable patterns: planning the whole municipal area while analysing a 1 km core around the temple in detail, or planning only a 2.5 sq. km temple precinct. For Tiruchendur we recommend the first pattern, covering the municipality with a detailed study of a 3.24 sq. km core of 18 wards. Pilgrim arrivals rose from 20,44,949 in 2017 to 34,62,602 in 2023, an increase of about 69 per cent, and this pressure is the main reason the town needs a plan now. The paper closes with a phased framework for the data collection, analysis and proposals that the second stage of the work will carry out.
