Tatsana Nakkhattaroek Pavilion, Phra Nakhon Khiri Historical Park. This circular pavilion, perched on the scenic heights of Khao Wang, was originally built for King Rama IV. It served as a royal lookout for observing the stars and enjoying festive fireworks displays over Phetchaburi. Today, it remains one of the most stunning viewpoints, offering a panoramic gaze across the historic city.
