Once home to European merchants and embassies, Bang Rak sits on the river bend between the Old City and Charoen Krung.
Bang Rak (which means 'Tamarind Forest Village') was home to European trading houses in the 19th century — the architecture still shows this history.
The Mandarin Oriental is in Bang Rak; the surrounding streets have heritage shophouses, churches (Assumption Cathedral), and old trading warehouses.
A mix of renovation and neglect — creative studios in old buildings, a handful of excellent restaurants, and the general movement along Charoen Krung.
Saphan Taksin BTS or express boat from the river; easily combined with a Charoen Krung walk.
