Brief history about Sri Mahamariamman Temple,Kuala Lumpur

Research is related to question number 2:

1)  What religion buildings did the other communities build in the same era/time?

   The building was built in year of  1873 by K. Thamboosamy Pillai (where as Sin Sze Si Ya Temple was built in the year 1864). The Sri Mahamariamman temple was only open to public in the year of 1920s. The temple now is known as the oldest and richest Hindu temple in Kuala Lumpur.

The building now is located in Chinatown along Jalan Tun H S Lee  after it was shifted from somewhere near Kuala Lumpur railway station. It is around 700 meters away from Sin Sze Si Ya temple which is situated at Leboh Pudu.The initial attap structure was demolished in 1887 and a brick building was erected in its place. That structure was demolished to make way for the current temple building which were completed in 1968. The impressive gateway to the temple, known as the gopuram, was completed in 1972. The new temple was consecrated in 1973.

Gopuram

Built in the South Indian style, the temple's most outstanding feature is the impressive 5-tiered gopuram (tower). It is the tallest structure in the temple. The dramatic 22.9m (75ft) high pyramid-shaped gate tower is decorated with depictions of Hindu gods sculpted by artisans from southern India. The chief sculptor was the late S. T. Muniappa from Tamil Nadu and is credited for creating the 228 idols on the gopuram.
