The canals of Amsterdam form powerful rings around the now non-existent city walls. At the eastern end, near Rembrandt Square, they all join the large and very wide Amstel Canal cut through with bascule bridges. The other bridges do not lift, so on the canals you can find only low boats full of tourists, and houses on barges moored here. The color of the canals corresponds to the color of the sky – sunny blue by day and black broken by the orange light of the lanterns at night. The most picturesque, however, is the deep and rich navy blue of the oncoming storm reflecting in the water, which slightly sloping facades of tenement houses bow to.
