The houses in Amsterdam are built on pilings and, because the piling settle, the houses shift with time. As a result, all the older buildings are a bit crooked. How the windows and doors in some of these houses can continue to operate in the crooked walls is beyond me. The Sint Nicolaaskerk is a Roman Catholic church in Amsterdam, built in Neo-Baroque and Neo-Renaissance styles. At the front of the church are two neo-Baroque towers with a rose window between them. The Hotel Di-Ann is an impressive structure composed of five buildings between the Herengracht and Keizersgracht canals.
