There are many types of collections. Some are formed by purposefully collecting certain objects, such as stamps or coins. However, some collections are only a byproduct of an obsession, a quirk of mind. For example, Paul Brockmann got into the habit of buying his girlfriend and later his wife a dress every time they went ballroom dancing. It might seem excessive to some, but it was his way of showing his affection. Overtime, this collection grew to be enormous, counting 55,000 dresses in total. Basic math tells us that either they went ballroom dancing three times per day for every day of their lives, or he bought them in huge bundles every time.

Grand banqueting halls, opulent lobbies and vast ballrooms; you could easily be forgiven for thinking this was a collection of photographs was documenting some of Europe’s grandest hotels. However, a closer look will reveal the majestic rooms to be engulfed in swathes of dust and moss; hotels that once hosted royals and high society abandoned to the elements. This is the latest result of urban exploration photography, going beyond “no entry” signs to capture images of dilapidated buildings across Europe. IT worker Thomas Windisch, from Graz in Austria, indulged his passion for photography by traveling across the continent, visiting over 100 abandoned hotels along the way.
