In recent years, a number of strange buildings, and monuments, have been built, some with the sole purpose of attracting tourists. While some of these constructions make sense, and even make a great holiday destination, others make us wonder how they were thought of to begin with. While we couldn’t list every unusual construction, below are 10 of the most unusual things built by humans.
