This was a beautiful Buddhist site that we came upon.
I read that it is actually a tribute to the special Makha Bucha event. Makha Bucha Day, also called Magha Puja Day or Sangha Day, is viewed as one of the most essential Buddhist festivals. This auspicious event refers to the worship that takes place on the full moon of the third lunar month (about the last weeks of February or early March) to celebrate the day on which Lord Buddha recounted the “Ovada Patimokkha” (the Important Teaching) to his devotees.
The place is a tribute to the revered Makha Bucha event in the Buddhist Calendar, when 1,250 disciples came to see the Buddha without being summoned. This is spectacularly represented here by the large gold Buddha surrounded by the symmetrically placed smaller gold statues of the disciples.
And goodness knows how many Buddhist statues there are in this park!!
But please be aware that there are people in Thailand who do not like the location being used like a tourist attraction - please show respect.
