Ambastala Dagaba (Sela Chethiya): The Sacred Stupa Where Buddhism Began in Sri Lanka

After climbing 1,840 ancient granite steps to the upper terrace of Mihintale, pilgrims and visitors are greeted by the Ambastala Dagaba (Sela Chethiya)—the very spot where Arahat Mahinda Thero, son of Emperor Ashoka, first met King Devanampiyatissa and introduced Buddhism to Sri Lanka in the 3rd century BCE.

This sacred stupa, built by King Mahadatika Mahanaga (9–21 CE), is one of Sri Lanka’s 16 Solosmasthana—holy sites believed to have been visited by the Buddha himself. According to ancient chronicles, it enshrines a precious relic: the Buddha’s Urna Roma (hair between the eyebrows).

Historical & Religious Significance

1. The Meeting That Changed Sri Lanka

The Mahavamsa records that this was where Mahinda Thero stood when he called out to King Devanampiyatissa, who was hunting deer. Their encounter marked the official introduction of Buddhism to the island, transforming Sri Lanka’s spiritual and cultural landscape forever.

2. A Stupa Built on Sacred Ground

  • Constructed by King Mahanaga (1st century CE) to commemorate this historic meeting.
  • Later expanded into a Vatadage (circular relic house) in the 2nd–3rd century under King Kanittha Tissa (164–192 CE).
  • Believed to have been restored by King Sirimeghavanna (303–311 CE) and later kings after Tamil invasions.

3. Connection to the Buddha’s Visits

Sela Chethiya is one of five stupas at Mihintale and among the 16 Solosmasthana, as tradition holds that the Buddha visited this spot during his third journey to Sri Lanka.

Architectural Marvels of Ambastala Dagaba

1. Unique Stupa Design

  • The dagaba has an unusual shape—between a bell and a "heap of paddy" (rice mound).
  • Surrounded by two rows of 12-foot-tall octagonal pillars, similar to those at Thuparama Dagaba in Anuradhapura.

2. The Pillars & Their Purpose

  • Each pillar features exquisitely carved capitals with:
    • Lions or hansa birds marching left.
    • Rows of dwarfs facing forward.
  • Scholars debate whether these pillars supported a wooden roof or were used to hang festival lanterns (Parker, 1909).

3. The Statues: A Silent Testimony

Two damaged stone statues stand near the stupa:

  1. A Headless Buddha Statue – Missing arms and head, yet radiating serenity.
  2. King Devanampiyatissa’s Statue – Once adorned with:
    • pear-shaped crown with a jeweled diadem.
    • Pendant earrings and a necklace.
    • lotus-flower base (similar to Thuparama’s design).

Ambastala Dagaba Today

Though partially ruined, the stupa remains a powerful pilgrimage site, especially during Poson Poya (June), when thousands commemorate Mahinda’s arrival. The Vatadage ruins, pillars, and statues evoke the grandeur of ancient Sri Lankan Buddhist architecture.

Conclusion

The Ambastala Dagaba (Sela Chethiya) is more than just an ancient stupa; it’s the hallowed ground where Buddhism took root in Sri Lanka. Whether you seek history, spirituality, or architectural wonder, this sacred site offers a profound connection to the island’s Buddhist heritage.
