Located just outside the city's old walls, the temple derives its name from the 300 teaks planted on the site around the time of its foundation.

[4] The best preserved part of the temple complex is its elaborate stupa 12.5 metres (41 ft) tall and featuring many ornamental stucco motifs.

[1] Particularly significant are the stucco images of Gautama Buddha, which are among the few remaining in situ examples from the Early Classic period.

Garuda figures associated with Hinduism and the Sukhothai Kingdom also adorn Wat Pa Sak's walls.

The Himavat Forest on the lower slopes of Meru is the domain of many mythical creatures, some of whom were chosen to guard sacred structures.
