Audioguida Su san farang, Bangkok

You are invited to the discovery of a less known protestant, then christian and also jewish graveyard, where the first westerners to have established business relationships in the early Bang-Kok rest in peace. 

This is a short trip from Saphan Taksin bridge, ending with a relaxing stop at the Ramada Plaza Hotel garden & pool a/o a tour in the new Asiatique the Riverfront night bazaar and entertainment venue. Best time to visit, if you wish to enjoy the latter place is then afternoon.
