Under the theme "Stronger Together with Street Art @ Ratchaprasong", they created street art, graffiti and installations to breathe new vitality and colour into the area after the deadly bombing in August that killed 20 and injured over a hundred people.
Among artists are street artist named P7, illustrator Patreeda Prasanthong, Singer-pop artist Oh Futon and painter Chalit nakpawan.
The 11 pieces will be exhibited across Ratchaprasong until October 18.
Creating the campaign is the Ratchaprasong Square Trade Association (RSTA), the grouping of hotels, shopping malls and small businesses located in the area.
