Here is a temple that easy to visit as it is located in Colombo, the commercial capital where the Bandaranaike International Airport is situated in.
The Gangaramaya Temple is one of the most important in Colombo because of its eclectic architecture that has Sri Lankan as well as Chinese, Indian and Thai influence. The temple is made up of several buildings that are located by the serene Beira Lake.
Within the temple premises, there are quite a few interesting components that you can visit such as the Vihara (temple), the Vihara Mandiraya, the Cetiya (Pagoda) the Bodhi tree, the Seema Malakaya (assembly hall for monks) and the Relic Chamber.
Every year in the month of February, the temple hosts the Navam Maha Perahera which is an extravagant display of Sri Lanka's culture.
