Perched on a ridge approximately 5 kilometers south of Thimphu, Simtokha Dzong holds the distinction of being the first dzong built in Bhutan, constructed by Zhabdrung Ngawang Namgyal in 1629. Although smaller in scale compared to Tashichho Dzong, its historical significance is immense, as it played a crucial role in the unification of Bhutan. Today, it serves as the Dzongkha language learning institute, a testament to its enduring cultural importance.

The dzong is particularly renowned for its exquisite and remarkably preserved wall paintings, which depict a rich array of deities, Buddhist figures, and mandalas. These vibrant artworks offer a rare glimpse into early Bhutanese artistic traditions and religious iconography. A visit to Simtokha Dzong provides a serene and insightful experience, allowing visitors to appreciate both the architectural heritage and the spiritual depth that characterize Bhutanese monastic life.
