A brief introduction to Bangkok
Known to locals as “Krung Thep”, meaning “City of Angels”, Bangkok is a sprawling metropolis that attracts visitors from across the world looking to get a taste of Thailand’s enchanting culture. From shopping at mega malls and bustling night markets, and even watching a Muay Thai boxing match, there’s plenty to do in Thailand’s capital.
Those interested in Thailand’s culture are recommended to visit Bangkok’s sacred temples, including the Wat Phra Keaw (Temple of the Emerald Buddha) as well as Wat Arun, and Wat Saket. For history lovers, consider visiting the opulent Grand Palace – a complex of buildings at the heart of Bangkok used as the official residence of the Kings of Thailand from 1782.
Bangkok is also a destination that is famous for its shopping and boasts luxury malls such as the Icon Siam, Central World, and Siam Paragon. If you wish to shop for something more local, visit Shilongjun Road where you can explore the area’s many stalls, galleries and concept stores.
Be sure to visit the newly renovated Asiatique, an old riverside warehouse that now houses an authentic night market alongside restaurants, bars, and small shops selling speciality goods.
