The Grachtengordel is the ring of canals everyone pictures when they picture Amsterdam. Three horseshoes of water lie one inside the next — Herengracht, Keizersgracht, Prinsengracht — with merchants' houses standing shoulder to shoulder along both banks of each. There is no entrance here and nothing to queue for, and no single view carries the place. The effect builds over a few hundred metres of bridges, brick, water and iron, so the walk matters more than the stopping.
The houses are narrow, deep and tall, and their gables date them: stepped ones are the earliest, then neck shapes, then bell shapes, then the flat classical fronts of the wealthy later years. Amsterdam had outgrown its walls, and from 1613 the city dug the three waterways as one surveyed project, sold off in standard plots and built out over most of a century. The whole ring is a UNESCO site. At dusk the bridges come on in strings of bulbs, the water turns black, and the houses read mostly as reflections in it.
