10. Frankfurt, Germany
Frankfurt is one of the biggest transportation hubs in the world and one of the largest financial centers in Europe. With so many people and money pouring into the city, it is surprising to find it on the list of most boring places, yet here it is. One of the reasons behind it is that Frankfurt was heavily bombed during the World War 2 and almost all of its old historic buildings that provide charm and authenticity to many German and European cities have been destroyed. Today, it is a modern metropolis of glass and concrete like so many others around the world. Despite many things it has to offer, Frankfurt was recommended by many tourist sites as a place best suited for a short visit at best.
