I love the architecture seen in Amsterdam. We did a canal boat tour on a wonderful sunny day and saw many examples of it.
Just one of many. All of them have beam sticking out at the top with hooks so furniture and other heavy objects can be pulled up to windows. Most of the houses are very narrow as they were charged more taxes if they were wide so they built up and back with rooms going deep.
We took a tour through the red light district. There were women sitting or standing behind windows available for business even in the afternoon. I wanted a photo of one but just didn’t feel comfortable doing it and I think they wouldn’t have liked it anyway. Most of them looked young and attractive to me. I guess they closed the curtain if a man came in.
