Wat Ton Kwen is renowned for its well-preserved and highly valuable traditional Lanna architecture.

It was registered as a historic site in 1983 and was later recognized as an Outstanding Conservation Building by the Association of Siamese Architects in 1989.

Later, the temple was renamed after Kruba In, a skilled craftsman who played a significant role in the construction of the viharn (main hall).

The wall behind the principal Buddha image features an arched niche adorned with metal votive tablets.
