Site-selection narrative — the Vel-shaped limestone formation
K. Thamboosamy Pillai (founder of the Sri Maha Mariamman Temple KL, 1873) identified the main cave entrance shape as resembling Murugan's divine Vel (spear) — this became the central reason for site-selection. Multi-source verified (Wikipedia + mytravellane + arupadai.org + omspiritualshop). Murti installed 1891; first Thaipusam 1892.
