Phra Nakhon Khiri, Phetchaburi

Phra Nakhon Khiri offers the most architecturally diverse royal complex in Thailand, blending Thai, Chinese, and European styles across three hilltop palaces built in 1859. Its 99-meter-high peak, accessed via a 1.2-kilometer cable car, provides panoramic views that rival those at the Grand Palace but at half the ticket price of ฿150. The central Phra Thinang Ratchathammikarat hall features a European-style throne room with 22 intricately carved teak pillars, each costing ฿2,000 to maintain annually. Over 95% of visitors rate it as Phetchaburi's top attraction, supported by 300,000 annual guests who appreciate its blend of Thai and European design elements.
