Sri Aruloli Thirumurugan Hindu Temple, also known as the Penang Hill Hindu Temple, is one of the oldest Hindu temples in Penang. This temple started as a small sanctuary dedicated to the Hindu deity Murugan in the 1800s. Murugan, also known as Karthikeya, Subramanya and Skanda, is the Hindu god of war. The devotees installed a Murugan Vel or trident on the place of the shrine. As years passed, the temple was rebuilt and enlarged with the help of its devotees.
