Even from the railroad tracks to Haarlem, you can see her rising up out of the old Amsterdam city center. With its three slender towers, the Posthoornkerk is an eye-catcher within walking distance of Central Station. Strolling down the busy Haarlemmerstraat, an intimate little square suddenly looms up behind more than a hundred-year-old trelliswork. Step inside and become enchanted by light and architecture.
