According to popular belief, a sadhu (holy man) chose a spot close to the waterfalls for a shrine dedicated to Murugan. The place was called thanner malai, meaning water hill, and the deity itself was known as Thannermalaian, The "old" Balathandayuthapani temple dates from 1850, when the British authorities took over the site of the Original Balathandayuthapani Temple, and provided the Hindus an eleven-acre plot of hillside land for their temple. The Balathandayuthapani temple became the focus of the annual Thaipusam celebrations since then.
At the foot of the staricase leading to the Balathandayuthapani temple is a shrine dedicated to the deity Ganesha. The Sree Ganeshar Temple has since developed into a separate temple in its own right, and with its own devoteesor "he who resides by the waterfall".
The Balathandayuthapani temple has undergone several major renovations. This is in keeping with the requirements of the Hindu agamid tenets, that renovations be done for every mamangam, or 12-year cycle. Over the years, as the number of devotees and worshippers increased, the Hindu Endowments Board found that the hill top temple could no longer accommodate the numbers. This is especially true in the past decade, with more and more visitors converging on the temple particularly during the Thaipusam celebration (other feast days of smaller scale include the Chitra Pournami, Kantha Sasthi, Thirukarthigai and Aadipournami).
A feasibility study was conducted to ascertain the viability of expanding the old hill top temple. Consultants engaged in the study discovered that the temple was sited over several subterranean springs. This makes its location unstable. After deliberating over the various reports, the Hindu Endowments Board made a decision to relocate the Balathandayuthapani temple to a new, safer location.
The new Arulmigu Balathandayuthapani temple is planned to accommodate up to 700,000 visitors, a number expected for every Thaipusam Festival. In keeping with its position as a major Hindu temple, it will have a huge maha mandapam, the pillared outer hall in which public rituals are performed.
Visitors to the new Arulmigu Balathandayuthapani Temple has an even longer climb than before, but the view makes the effort worthwhile. With over 500 steps (some estimates put the figure at 512 steps, though this is difficult to judge, as there are more than one route to the top), it is longer than the 272 steps up Batu Caves.
The winding route allows you to stop several times to enjoy the scenery. Half way to the top, you arrive at the Old Hill Top Murugan Temple, the former site for the Thaipusam celebrations. Next to it is the Arulmamani Arumugam Pillai Mandapam, a pavilion built in 1956. It acts as a staging area for visitors and pilgrims. From here, you get a good view of the new Arulmugam Balathandayuthapani Temple before you continue your ascend. As you climb higher, the skyscrapers of Gurney Drive and eventually the rest of George Town come into view.
Arriving at the top, you enter the temple through a main gate topped by a gigantic seven-storey rajagopuram, or kingly temple tower, which is intricately embellished with multi-tier statues of deities. The maha mandapam surrounds the garbhagriha, or sanctum sanctorum, where the image of Murugan is placed. There will also be alcoves or shrines for other deities.
The maha mandapam is supported by rows of intricately carved pillars. Hanging down from the ceiling are chandeliars that cast their light over the well-polished floor. Devotees gather in groups on the floor or awaiting their turn to perform prayers and rituals.
