26. Crystal Palace, London
Speaking of the Crystal Palace, this site has also made it to the list. The Crystal Palace in London was a Victorian-style building made of glass, wood and cast iron, which made the majority of the building almost entirely see-through.

It was specifically created for the Great Exhibition, a world exhibition that was intended to attract visitors from all over to display various steps forward in culture and industry. Six million people visited the palace for the event, and it has become a famous symbol of the Victorian era. Tragically, much like its successor, the Crystal Palace burned in a fire.
