Is there any closer (in any sense!) big friend of Cologne than the Netherlands? Amstel is a renowned river, a beer make, but also a lovely quarter in Amsterdam, fascinating by its unique ‘Dancing Houses’ ensemble. Houses there lean to each other, making them look like they dance and sway. Many families in Cologne have personal family connections in Amsterdam, Utrecht, Maastricht, Rotterdam and many other lovely Dutch locations. It is a tribute to our friend and family ties with the beautiful Netherlands. So Dom also came to Amsterdam to his relatives for a dance. Blame the authors for not keeping the proportions.
