The Rattanakosin Island area is the formerly walled town surrounded by waterways -- the Chao Phraya River and the Old Moat -- and so known as the Old Town.
This section covers the areas of 'Inner Rattanakosin' and 'Middle Rattanakosin' in the map, marked with blue and pink colours respectively (see the symbols indicating the colours of the different areas in the box on the lower part of the map). Situated here are the Grand Palace, the Temple of the Emerald Buddha, the Temple of the Reclining Buddha and a few other famous Buddhist temples, the Giant Swing and sections of the ancient city walls.
The Chinatown area is located just to the southeast of the Old Town in the 'Outer Rattanakosin' area in the map, marked with green colour. Major roads are Yaowarat, Chareon Krung, Song Wat and Sampheng. It is an early settlement of Chinese immigrants who were moved here from the Old Town at the time of establishment of Bangkok as the new capital. It is still a thriving commercial area particularly well known for its dozens of gold shops.
