This is where the 19th-century port of Bangkok used to be. Now it is a crumbling building that needs a lot of renovation to get back into a useful state, but its obvious that this grand colonial-style home was once the pride of the area. It was built in the 1880s and used to levy taxes on traders that moved in and out of Siam. It’s not open to the public, but you can walk around and try to grasp the atmosphere of Bangkok in earlier times. It was used in Wong Kar-wai’s ”In the Mood for Love”, a great film worth the watch.
