The centre of Willemstad has loads of interesting architecture to merit some interest, but its original and colourful public street art signs also have plenty of artistic value. While multinational companies promote their brands by spending millions on ad agencies, local supermarkets, beauty salons and restaurants market themselves with elaborately painted advertisements on their walls. Political art is also quite popular, not to mention murals with erotic themes. Dushi Walk organises guided tours of street art on Tuesdays, Wednesdays and Thursdays (09:00, NAF 25) in the centre of Willemstad.
