Below we are about to list and describe a few of the most important and ancient coffee houses of all times, trying to point out how they originated, became important and, at last, still fascinate thousands of visitors and consumers today. According to the historians, the earliest record of a coffee house is to be considered back to 1475. It seems a shop named Kiva Han opened at that time in Istanbul, namely Constantinople, as the city was called then. The café was likely to serve Turkish coffee , which is still widely popular today, soon followed by filtered coffee.
