Just down the street, Haarlem’s top museum features the work of its most famous son: the great portrait artist Frans Hals. Here, in a room full of his masterpieces, we get a good taste of Protestant Dutch art. Dutch society was a merchant society, and now artists worked for a new kind of customer…Merchants. Haarlem’s Grote Kerk, or “great church,” towers over the market square as if to bless all the business that takes place below. Haarlem’s towering organ has been giving worship here an inspirational soundtrack since 1738.
