Thailand is live on Travelog with three cities: Bangkok, Phuket, and Pattaya. None of these three cities carry a UNESCO World Heritage listing, since Thailand's actual UNESCO sites, Sukhothai and Ayutthaya, sit elsewhere. Bangkok is anchored instead to the Grand Palace, seat of the Thai monarchy for 150 years; Phuket to Sirinat National Park; and Pattaya to the Sanctuary of Truth, a still-under-construction wooden temple. Ayutthaya, the actual UNESCO site, is covered as a landmark-tier day trip from Bangkok.
None of Thailand's three most-visited cities carry UNESCO status, but each has genuine, verified anchors worth understanding honestly rather than a UNESCO claim that doesn't apply, all three covered in full below.
